The Debian GNU/Linux FAQ
<br>Chapter 1 - Definitions and overview
</h1>
<hr>
<h2><a name="s-whatisfaq"></a>1.1 What is this FAQ?</h2>
<p>
This document gives frequently asked questions (with their answers!) about the
Debian distribution (Debian GNU/Linux and others) and about the Debian project.
If applicable, pointers to other documentation will be given: we won't quote
large parts of external documentation in this document. You'll find out that
some answers assume some knowledge of Unix-like operating systems. We'll try
to assume as little prior knowledge as possible: answers to general beginners
questions will be kept simple.
</p>
<p>
If you can't find what you're looking for in this FAQ, be sure to check out <a
href="ch-support.en.html#s-debiandocs">What other documentation exists on and
for a Debian system?, Section 12.1</a>. If even that doesn't help, refer to <a
href="ch-faqinfo.en.html#s-feedback">Feedback, Section 16.2</a>.
</p>
<hr>
<h2><a name="s-whatisdebian"></a>1.2 What is Debian GNU/Linux?</h2>
<p>
Debian GNU/Linux is a particular <em>distribution</em> of the Linux operating
system, and numerous packages that run on it.
</p>
<p>
Debian GNU/Linux is:
</p>
<ul>
<li>
<p>
<strong>full featured</strong>: Debian includes more than 18200 software
packages at present. Users can select which packages to install; Debian
provides a tool for this purpose. You can find a list and descriptions of the
packages currently available in Debian at any of the Debian <code><a
href="http://www.debian.org/distrib/ftplist">mirror sites</a></code>.
</p>
</li>
</ul>
<ul>
<li>
<p>
<strong>free to use and redistribute</strong>: There is no consortium
membership or payment required to participate in its distribution and
development. All packages that are formally part of Debian GNU/Linux are free
to redistribute, usually under terms specified by the GNU General Public
License.
</p>
<p>
The Debian FTP archives also carry approximately 560 software packages (in the
<samp>non-free</samp> and <samp>contrib</samp> sections), which are
distributable under specific terms included with each package.
</p>
</li>
</ul>
<ul>
<li>
<p>
<strong>dynamic</strong>: With about 1060 volunteers constantly contributing
new and improved code, Debian is evolving rapidly. The FTP archives are
updated twice every day.
</p>
</li>
</ul>
<p>
Most Linux users run a specific <em>distribution</em> of Linux, like Debian
GNU/Linux. However, in principle, users could obtain the Linux kernel via the
Internet or from elsewhere, and compile it themselves. They could then obtain
source code for many applications in the same way, compile the programs, then
install them into their systems. For complicated programs, this process can be
not only time-consuming but error-prone. To avoid it, users often choose to
obtain the operating system and the application packages from one of the Linux
distributors. What distinguishes the various Linux distributors are the
software, protocols, and practices they use for packaging, installing, and
tracking applications packages on users' systems, combined with installation
and maintenance tools, documentation, and other services.
</p>
<p>
Debian GNU/Linux is the result of a volunteer effort to create a free,
high-quality Unix-compatible operating system, complete with a suite of
applications. The idea of a free Unix-like system originates from the GNU
project, and many of the applications that make Debian GNU/Linux so useful were
developed by the GNU project.
</p>
<p>
For Debian, free has the GNUish meaning (see the <code><a
href="http://www.debian.org/social_contract#guidelines">Debian Free Software
Guidelines</a></code>). When we speak of free software, we are referring to
freedom, not price. Free software means that you have the freedom to
distribute copies of free software, that you receive source code or can get it
if you want it, that you can change the software or use pieces of it in new
free programs; and that you know you can do these things.
</p>
<p>
The Debian Project was created by Ian Murdock in 1993, initially under the
sponsorship of the Free Software Foundation's GNU project. Today, Debian's
developers think of it as a direct descendent of the GNU project.
</p>
<p>
Although Debian GNU/Linux itself is free software, it is a base upon which
value-added Linux distributions can be built. By providing a reliable,
full-featured base system, Debian provides Linux users with increased
compatibility, and allows Linux distribution creators to eliminate duplication
of effort and focus on the things that make their distribution special. See <a
href="ch-redistrib.en.html#s-childistro">I am making a special Linux
distribution for a &quot;vertical market&quot;. Can I use Debian GNU/Linux for
the guts of a Linux system and add my own applications on top of it?, Section
14.3</a> for more information.
</p>
<hr>
<h2><a name="s-linux"></a>1.3 OK, now I know what Debian is... what is Linux?!</h2>
<p>
In short, Linux is the kernel of a Unix-like operating system. It was
originally designed for 386 (and better) PCs; today Linux also runs on a dozen
of other systems. Linux is written by Linus Torvalds and many computer
scientists around the world.
</p>
<p>
Besides its kernel, a &quot;Linux&quot; system usually has:
</p>
<ul>
<li>
<p>
a file system that follows the Linux Filesystem Hierarchy Standard <code><a
href="http://www.pathname.com/fhs/">http://www.pathname.com/fhs/</a></code>.
</p>
</li>
</ul>
<ul>
<li>
<p>
a wide range of Unix utilities, many of which have been developed by the GNU
project and the Free Software Foundation.
</p>
</li>
</ul>
<p>
The combination of the Linux kernel, the file system, the GNU and FSF
utilities, and the other utilities are designed to achieve compliance with the
POSIX (IEEE 1003.1) standard; see <a href="ch-compat.en.html#s-otherunices">How
source code compatible is Debian with other Unix systems?, Section 4.3</a>.
</p>
<p>
For more information about Linux, see <code><a
href="http://www.linux.org/info/">What is Linux</a></code> by <code><a
href="http://www.linux.org/">Linux Online</a></code>.
</p>
<hr>
<h2><a name="s-non-linux"></a>1.4 Does Debian just do GNU/Linux?</h2>
<p>
Currently, Debian is only available for Linux, but with Debian GNU/Hurd and
Debian on BSD kernels, we have started to offer non-Linux-based OSes as a
development, server and desktop platform, too. However, these non-linux ports
are not officially released yet.
</p>
<p>
The oldest porting effort is Debian GNU/Hurd.
</p>
<p>
The Hurd is a set of servers running on top of the GNU Mach microkernel.
Together they build the base for the GNU operating system.
</p>
<p>
Please see <code><a
href="http://www.gnu.org/software/hurd/">http://www.gnu.org/software/hurd/</a></code>
for more information about the GNU/Hurd in general, and <code><a
href="http://www.debian.org/ports/hurd/">http://www.debian.org/ports/hurd/</a></code>
for more information about Debian GNU/Hurd.
</p>
<p>
A second effort is the port to a BSD kernel. People are working with both the
NetBSD and the FreeBSD kernels.
</p>
<p>
See <code><a
href="http://www.debian.org/ports/#nonlinux">http://www.debian.org/ports/#nonlinux</a></code>
for more information about these non-linux ports.
</p>
<hr>
<h2><a name="s-difference"></a>1.5 What is the difference between Debian GNU/Linux and other Linux distributions? Why should I choose Debian over some other distribution?</h2>
<p>
These key features distinguish Debian from other Linux distributions:
</p>
<dl>
<dt>Freedom:</dt>
<dd>
<p>
As stated in the <code><a href="http://www.debian.org/social_contract">Debian
Social Contract</a></code>, Debian will remain 100% free. Debian is very
strict about shipping truly free software. The guidelines used to determine if
a work is &quot;free&quot; are provided in <code><a
href="http://www.debian.org/social_contract#guidelines">The Debian Free
Software</a></code>.
</p>
</dd>
</dl>
<dl>
<dt>The Debian package maintenance system:</dt>
<dd>
<p>
The entire system, or any individual component of it, can be upgraded in place
without reformatting, without losing custom configuration files, and (in most
cases) without rebooting the system. Most Linux distributions available today
have some kind of package maintenance system; the Debian package maintenance
system is unique and particularly robust (see <a
href="ch-pkg_basics.en.html">Basics of the Debian package management system,
Chapter 7</a>).
</p>
</dd>
</dl>
<dl>
<dt>Open development:</dt>
<dd>
<p>
Whereas other Linux distributions are developed by individuals, small, closed
groups, or commercial vendors, Debian is the only major Linux distribution that
is being developed cooperatively by many individuals through the Internet, in
the same spirit as Linux and other free software.
</p>
<p>
More than 1060 volunteer package maintainers are working on over 18200 packages
and improving Debian GNU/Linux. The Debian developers contribute to the
project not by writing new applications (in most cases), but by packaging
existing software according to the standards of the project, by communicating
bug reports to upstream developers, and by providing user support. See also
additional information on how to become a contributor in <a
href="ch-contributing.en.html#s-contrib">How can I become a Debian software
developer?, Section 13.1</a>.
</p>
</dd>
</dl>
<dl>
<dt>The Universal Operating System:</dt>
<dd>
<p>
Debian comes with <code><a href="http://packages.debian.org/stable/">more than
18200 packages</a></code> and runs on <code><a
href="http://www.debian.org/ports/">11 architectures</a></code>. This is far
more than is available for any other GNU/Linux distribution. See <a
href="ch-software.en.html#s-apps">What types of applications and development
software are available for Debian GNU/Linux?, Section 5.1</a> for an overview
of the provided software and see <a href="ch-compat.en.html#s-arches">On what
hardware architectures/systems does Debian GNU/Linux run?, Section 4.1</a> for
a description of the supported hardware platforms.
</p>
</dd>
</dl>
<dl>
<dt>The Bug Tracking System:</dt>
<dd>
<p>
The geographical dispersion of the Debian developers required sophisticated
tools and quick communication of bugs and bug-fixes to accelerate the
development of the system. Users are encouraged to send bugs in a formal
style, which are quickly accessible by WWW archives or via e-mail. See
additional information in this FAQ on the management of the bug log in <a
href="ch-support.en.html#s-buglogs">Are there logs of known bugs?, Section
12.4</a>.
</p>
</dd>
</dl>
<dl>
<dt>The Debian Policy:</dt>
<dd>
<p>
Debian has an extensive specification of our standards of quality, the Debian
Policy. This document defines the qualities and standards to which we hold
Debian packages.
</p>
</dd>
</dl>
<p>
For additional information about this, please see our web page about <code><a
href="http://www.debian.org/intro/why_debian">reasons to choose
Debian</a></code>.
</p>
<hr>
<h2><a name="s-gnu"></a>1.6 How does the Debian project fit in or compare with the Free Software Foundation's GNU project?</h2>
<p>
The Debian system builds on the ideals of free software first championed by the
<code><a href="http://www.gnu.org/">Free Software Foundation</a></code> and in
particular by <code><a href="http://www.stallman.org/">Richard
Stallman</a></code>. FSF's powerful system development tools, utilities, and
applications are also a key part of the Debian system.
</p>
<p>
The Debian Project is a separate entity from the FSF, however we communicate
regularly and cooperate on various projects. The FSF explicitly requested that
we call our system &quot;Debian GNU/Linux&quot;, and we are happy to comply
with that request.
</p>
<p>
The FSF's long-standing objective is to develop a new operating system called
GNU, based on <code><a
href="http://www.gnu.org/software/hurd/">Hurd</a></code>. Debian is working
with FSF on this system, called <code><a
href="http://www.debian.org/ports/hurd/">Debian GNU/Hurd</a></code>.
</p>
<hr>
<h2><a name="s-pronunciation"></a>1.7 How does one pronounce Debian and what does this word mean?</h2>
<p>
The project name is pronounced Deb'-ee-en, with a short e in Deb, and emphasis
on the first syllable. This word is a contraction of the names of Debra and
Ian Murdock, who founded the project. (Dictionaries seem to offer some
ambiguity in the pronunciation of Ian (!), but Ian prefers ee'-en.)

The Debian GNU/Linux FAQ
<br>Chapter 3 - Choosing a Debian distribution
</h1>
<hr>
<p>
There are many different Debian distributions. Choosing the proper Debian
distribution is an important decission. This section covers some information
useful for users that want to make the choice best suited for their system and
also answers possible questions that might be arising during the process. It
does not deal with &quot;why you should choose Debian&quot; but rather
&quot;which distribution of Debian&quot;.
</p>
<p>
For more information on the available distributions read <a
href="ch-ftparchives.en.html#s-dists">How many Debian distributions are there?,
Section 6.1</a>.
</p>
<hr>
<h2><a name="s3.1"></a>3.1 Which Debian distribution (stable/testing/unstable) is better for me?</h2>
<p>
The answer is a bit complicated. It really depends on what you intend to do.
One solution would be to ask a friend who runs Debian. But that does not mean
that you cannot make an independent decision. In fact, you should be able to
decide once you complete reading this chapter.
</p>
<ul>
<li>
<p>
If security or stability are at all important for you: install stable. period.
This is the most preferred way.
</p>
</li>
</ul>
<ul>
<li>
<p>
If you are a new user installing to a desktop machine, start with stable. Some
of the software is quite old, but it's the least buggy environment to work in.
You can easily switch to the more modern unstable once you are a little more
confident.
</p>
</li>
</ul>
<ul>
<li>
<p>
If you are a desktop user with some experience in Linux and does not mind
facing the odd bug now and then, use unstable. It has all the latest and
greatest software, and bugs are usually fixed swiftly.
</p>
</li>
</ul>

<p>
If you are running a server, especially one that has strong stability
requirements or is exposed to the Internet, install stable. This is by far the
strongest and safest choice.
</p>
</li>
</ul>
<p>
The following questions (hopefully) provide more detail on these choices.
After reading this whole FAQ, if you still could not make a decision, stick
with the stable distribution.
</p>
<hr>
<h3><a name="s3.1.1"></a>3.1.1 You asked me to install stable, but in stable so and so hardware is not detected/working. What should I do?</h3>
<p>
Try to search the web using a search engine and see if someone else is able to
get it working in stable. Most of the hardware should work fine with stable.
But if you have some state-of-the-art, cutting edge hardware, it might not work
with stable. If this is the case, you might want to install/upgrade to
unstable.
</p>
<p>
For laptops, <code><a
href="http://www.linux-on-laptops.com/">http://www.linux-on-laptops.com/</a></code>
is a very good website to see if someone else is able to get it to work under
Linux. The website is not specific to Debian, but is nevertheless a tremendous
resource. I am not aware of any such website for desktops.
</p>
<p>
Another option would be to ask in the debian-user mailing list by sending an
email to debian-user@lists.debian.org . Messages can be posted to the list
even without subscribing. The archives can be read through <code><a
href="http://lists.debian.org/debian-user/">http://lists.debian.org/debian-user/</a></code>
Information regarding subscribing to the list can be found at the location of
archives. You are strongly encourage to post your questions on the
mailing-list than on <code><a
href="http://www.debian.org/support">irc</a></code>. The mailing-list messages
are archived, so solution to your problem can help others with the same issue.

<h3><a name="s3.1.2"></a>3.1.2 Will there be different different versions of packages in different distributions?</h3>
<p>
Yes. Unstable has the most recent (latest) versions. But the packages in
unstable are not well tested and might have bugs.
</p>
<p>
On the other hand, stable contains old versions of packages. But this package
is well tested and is less likely to have any bugs.
</p>
<p>
The packages in testing fall between these two extremes.
</p>
<hr>
<h3><a name="s3.1.3"></a>3.1.3 The stable distributions really contains outdated packages. Just look at Kde, Gnome, Xorg or even the kernel. They are very old. Why is it so?</h3>
<p>
Well, you might be correct. The age of the packages at stable depends on when
the last release was made. Since there is typically over 1 year between
releases you might find that stable contains old versions of packages.
However, they have been tested in and out. One can confidently say that the
packages do not have any known severe bugs, security holes etc., in them. The
packages in stable integrate seamlessly with other stable packages. These
characteristics are very important for production servers which have to work 24
hours a day, 7 days a week.
</p>
<p>
On the other hand, packages in testing or unstable can have hidden bugs,
security holes etc., Moreover, some packages in testing and unstable might not
be working as intended. Usually people working on a single desktop prefer
having the latest and most modern set of packages. Unstable is the solution
for this group of people.
</p>
<p>
As you can see, stability and novelty are two opposing ends of the spectrum.
If stability is required: install stable distribution. If you want to work
with the latest packages, then install unstable.
</p>
<hr>
<h3><a name="s3.1.4"></a>3.1.4 If I were to decide to change to another distribution, Can I do that?</h3>
<p>
Yes, but it is a one way process. You can go from stable --&gt; testing --&gt;
unstable. But the reverse direction is not &quot;possible&quot;. So better be
sure if you are planning to install/upgrade to unstable.
</p>
<p>
Actually, if you are an expert and if you are willing to spend some time and if
you are real careful and if you know what you are doing, then it might be
possible to go from unstable to testing and then to stable. The installer
scripts are not designed to do that. So in the process, your configuration
files might be lost and....
</p>
<hr>
<h3><a name="s3.1.5"></a>3.1.5 Could you tell me whether to install testing or unstable?</h3>
<p>
This is a rather subjective issue. There is no perfect answer but only a
&quot;wise guess&quot; could be made while deciding between unstable and
testing. My personal order of preference is Stable, Unstable and Testing. The
issue is like this:
</p>
<ul>
<li>
<p>
Stable is rock solid. It does not break.
</p>
</li>
</ul>
<ul>
<li>
<p>
Testing breaks less often than Unstable. But when it breaks, it takes a long
time for things to get rectified. Sometimes this could be days and it could be
months at times.
</p>
</li>
</ul>
<ul>
<li>
<p>
Unstable changes a lot, and it can break at any point. However, fixes get
rectified in many occasions in a couple of days and it always has the latest
releases of software packaged for Debian.
</p>
</li>
</ul>
<p>
But there are times when tracking testing would be beneficial as opposed to
unstable. The author such situation due to the gcc transition from gcc3 to
gcc4. He was trying to install the <code>labplot</code> package on a machine
tracking unstable and it could not be installed in unstable as some of its
dependencies have undergone gcc4 transition and some have not. But the package
in testing was installable on a testing machine as the gcc4 transitioned
packages had not &quot;trickled down&quot; to testing.
</p>
<hr>
<h3><a name="s3.1.6"></a>3.1.6 You are talking about testing being broken. What do you mean by that?</h3>
<p>
Sometimes, a package might not be installable through package management tools.
Sometimes, a package might not be available at all, maybe it was (temporarily)
removed due to bugs or unmet dependencies. Sometimes, a package installs but
does not behave in the proper way.
</p>
<p>
When these things happen, the distribution is said to be broken (at least for
this package).
</p>
<hr>
<h3><a name="s3.1.7"></a>3.1.7 Why is it that testing could be broken for months? Wont the fixes introduced in unstable flow directly down into testing?</h3>
<p>
The bug fixes and improvements introduced in the unstable distribution trickle
down to testing after a certain number of days. Let's say this threshold is 10
days. The packages in unstable go into testing only when there are no RC-bugs
reported against them. If there is a RC-bug filed against a package in
unstable, it will not go into testing after the 10 days.
</p>
<p>
The idea is that, if the package has any problems, it would be discovered by
people using unstable and will be fixed before it enters testing. This keeps
the testing in an usable state for most period of the time. Overall a
brilliant concept, if you ask me. But things are alwasy not so simple.
Consider the following situation:
</p>
<ul>
<li>
<p>
Imagine you are interested in package XYZ.
</p>
</li>
</ul>
<ul>
<li>
<p>
Let's assume that on June 10, the version in testing is XYZ-3.6 and in unstable
it is XYZ-3.7
</p>
</li>
</ul>
<ul>
<li>
<p>
After 10 days, XYZ-3.7 from unstable migrates into testing.
</p>
</li>
</ul>
<ul>
<li>
<p>
So on June 20, both testing and unstable have XYZ-3.7 in their repositories.
</p>
</li>
</ul>
<ul>
<li>
<p>
Let's say, The user of testing distribution sees that a new XYZ package is
available and updates his XYZ-3.6 to XYZ-3.7
</p>
</li>
</ul>
<ul>
<li>
<p>
Now on June 25, someone using testing or unstable discovers an RC bug in
XYZ-3.7 and files it in the BTS.
</p>
</li>
</ul>
<ul>
<li>
<p>
The maintainer of XYZ fixes this bug and uploads it to unstable say on June 30.
Here it is assumed that it takes 5 days for the maintainer to fix the bug and
upload the new version. The number 5 should not be taken literally. It could
be less or more, depending upon the severity of the RC-bug at hand.
</p>
</li>
</ul>
<ul>
<li>
<p>
This new version in unstable, XYZ-3.8 is scheduled to enter testing on July
10th.
</p>
</li>
</ul>
<ul>
<li>
<p>
But on July 5th some other person, discovers another RC-bug in XYZ-3.8
</p>
</li>
</ul>
<ul>
<li>
<p>
Let's say the maintainer of XYZ fixes this new RC-bug and uploads new version
of XYZ after 5 days.
</p>
</li>
</ul>
<ul>
<li>
<p>
So on July 10, testing has XYZ-3.7 while unstable has XYZ-3.9
</p>
</li>
</ul>
<ul>
<li>
<p>
This new version XYZ-3.9 is now rescheduled to enter testing on July 20th.
</p>
</li>
</ul>
<ul>
<li>
<p>
Now since you are running testing, and since XYZ-3.7 is buggy, you could
probably use XYZ only after July 20th. That is you essentially ended up with a
broken XYZ for about one month.
</p>
</li>
</ul>
<p>
The situation can get much more complicated, if say, XYZ depends on 4 other
packages. This could in turn lead to unusable testing distribution for months.
The above scenario which is artificially created by me, can occur in the real
life. But such occurrences are rare.
</p>

<h3><a name="s3.1.8"></a>3.1.8 From an administrator's point of view, Which distribution requires more attention?</h3>
<p>
One of the main reasons many people chose Debian over other Linux distributions
is that it requires very little administration. People want a system that just
works. In general one can say that, stable requires very little maintenance
while testing and unstable require constant maintenance from the administrator.
If you are running stable, all you need to worry about is, keeping track of
security updates. If you are running either testing or unstable it is a good
idea to be aware of the new bugs discovered in the installed packages, new
bugfixes/features introduced etc.
</p>
<hr>
<h3><a name="s3.1.9"></a>3.1.9 What happens when a new release is made?</h3>
<p>
This question will not help you in choosing a Debian distribution. But sooner
or later you will face this question.
</p>
<p>
The stable distribution is currently etch; The next stable distribution will be
called as lenny. Let's consider the particular case as to what happens when
lenny is released as the new stable version.
</p>
<ul>
<li>
<p>
oldstable = sarge; stable = etch; testing = lenny; unstable = sid
</p>
</li>
</ul>
<ul>
<li>
<p>
Unstable is always referred to as sid irrespective of whether a release is made
or not.
</p>
</li>
</ul>
<ul>
<li>
<p>
packages constantly migrate from sid to testing (i.e. lenny). But packages in
stable (i.e. etch) remain the same except for security updates.
</p>
</li>
</ul>
<ul>
<li>
<p>
after sometime testing becomes frozen. But it will still be called testing.
At this point no new packages from unstable can migrate to testing unless they
include release-critical (RC) bug fixes.
</p>
</li>
</ul>
<ul>
<li>
<p>
When testing is frozen, all the new bugfixes introduced, have to be manualy
checked by the members of the release team. This is done to ensure that there
wont be any unknown severe problems in the frozen testing.
</p>
</li>
</ul>
<ul>
<li>
<p>
RC bugs in 'frozen testing' are reduced to zero.
</p>
</li>
</ul>
<ul>
<li>
<p>
The 'frozen testing' with no rc-bugs will be released as the new stable
version. In our example, this new stable release will be called as lenny.
</p>
</li>
</ul>
<ul>
<li>
<p>
At this stage oldstable = etch, stable = lenny. The contents of stable and
'frozen testing' are same at this point.
</p>
</li>
</ul>
<ul>
<li>
<p>
A new testing is forked from the current stable.
</p>
</li>
</ul>
<ul>
<li>
<p>
Packages start coming down from sid to testing and the Debian community will be
working towards making the next stable release.
</p>
</li>
</ul>
<hr>
<h3><a name="s3.1.10"></a>3.1.10 I have a working Desktop/cluster with Debian installed. How do I know which distribution I am running?</h3>
<p>
In most situations it is very easy to figure this out. Take a look at the
<code>/etc/apt/sources.list</code> file. There will be an entry similar to
this:
</p>
<pre>
deb http://ftp.us.debian.org/debian/ unstable main contrib
</pre>
<p>
The third field ('unstable' in the above example) indicates the Debian
distribution the system is currently tracking.
</p>
<p>
You can also use <code>lsb_release</code> (available in the
<code>lsb-release</code> package). If you run this program in an unstable
system you will get:
</p>
<pre>
$ lsb_release -a
LSB Version: core-2.0-noarch:core-3.0-noarch:core-3.1-noarch:core-2.0-ia32:core-3.0-ia32:core-3.1-ia32
Distributor ID: Debian
Description: Debian GNU/Linux unstable (sid)
Release: unstable
Codename: sid
</pre>
<p>
However, this is always not that easy. Some systems might have
<code>sources.list</code> files with multiple entries corresponding to
different distributions. This could happen if the administrator is tracking
different packages from different Debian distributions. This is frequently
referred to as apt-pinning. These systems might run a mixture of
distributions.
</p>
<hr>
<h3><a name="s3.1.11"></a>3.1.11 I am currently tracking stable. Can I change to testing or unstable? If so, How?</h3>
<p>
If you are currently running stable, then in the
<code>/etc/apt/sources.list</code> file the third field will be either etch or
stable. You need to change this to the distribution you want to run. If you
want to run testing, then change the third field of
<code>/etc/apt/sources.list</code> to testing. If you want to run unstable,
then change the third field to unstable.
</p>
<p>
Currently testing is called lenny. So, if you change the third field of
<code>/etc/apt/sources.list</code> to lenny, then also you will be running
testing. But when lenny becomes stable, you will still be tracking lenny.
</p>
<p>
Unstable is always called Sid. So if you change the third field of
<code>/etc/apt/sources.list</code> to sid, then you will be tracking unstable.
</p>
<p>
Currently Debian offers security updates for testing but not for unstable, as
fixes in unstable are directly made to the main archive. So if you are running
unstable make sure that you remove the lines relating to security updates in
<code>/etc/apt/sources.list</code>.
</p>
<p>
If there is a release notes document available for the distribution you are
upgrading to (even though it has not yet been released) it would be wise to
review it, as it might provide information on how you should upgrade to it.
</p>
<p>
Nevertheless, once you make the above changes, you can run <code>aptitude
update</code> and then install the packages that you want. Notice that
installing a package from a different distribution might automatically upgrade
half of your system. If you install individual packages you will end up with a
system running mixed distributions.
</p>
<p>
It might be best in some situations to just fully upgrade to the new
distribution running <code>apt-get dist-upgrade</code>, <code>aptitude
safe-upgrade</code> or <code>aptitude full-upgrade</code>. Read apt's and
aptitude's manual pages for more information.
</p>
<hr>
<h3><a name="s3.1.12"></a>3.1.12 I am currently tracking testing (lenny). What will happen when a release is made? Will I still be tracking testing or will my machine be running the new stable distribution?</h3>
<p>
It depends on the entries in the <code>/etc/apt/sources.list</code> file. If
you are currently tracking testing, these entries are similar to either:
</p>
<pre>
deb http://ftp.us.debian.org/debian/ testing main
</pre>
<p>
or
</p>
<pre>
deb http://ftp.us.debian.org/debian/ lenny main
</pre>
<p>
If the third field in <code>/etc/apt/sources.list</code> is 'testing' then you
will be tracking testing even after a release is made. So after lenny is
released, you will be running a new Debian distribution which will have a
different codename. Changes might not be apparent at first but will be evident
as soon as new packages from unstable go over to the testing distribution.
</p>
<p>
But if the third field contains 'lenny' then you will be tracking stable (since
lenny will then be the new stable distribution).
</p>
<hr>
<h3><a name="s3.1.13"></a>3.1.13 I am still confused. What did you say I should install?</h3>
<p>
If unsure, the best bet would be stable distribution.
</p>
<hr>
<h2><a name="s3.2"></a>3.2 But what about Knoppix, Linex, Ubuntu, and others?</h2>
<p>
They are not Debian; they are <em>Debian based</em>. Though there are many
similarities and commonalities between them, there are also crucial
differences.
</p>
<p>
All these distributions have their own merits and are suited to some specific
set of users. For more information, read the information of <code><a
href="http://www.debian.org/misc/children-distros">software distributions based
on Debian</a></code> available at the Debian website.
</p>
<hr>
<h3><a name="s3.2.1"></a>3.2.1 I know that Knoppix/Linex/Ubuntu/... is Debian-based. So after installing it on the hard disk, can I use 'apt' package tools on it?</h3>
<p>
These distributions are Debian based. But they are not Debian. You will be
still able to use apt package tools by pointing the
<code>/etc/apt/sources.list</code> file to these distributions' repositories.
But then you are not running Debian, you are running a different distribution.
They are not the same.
</p>
<p>
In most situations if you stick with one distribution you should use that and
not mix packages from other distributions. Many common breakages arise due to
people running a distribution and trying to install Debian packages from other
distributions. The fact that they use the same formatting and name (.deb) does
not make them inmediately compatible.
</p>
<p>
For example, Knoppix is a Linux distribution designed to be booted as a live CD
where as Debian is designed to be installed on hard-disk. Knoppix is great if
you want to know whether a particular hardware works, or if you want to
experience how a linux system 'feels' etc., Knoppix is good for demonstration
purposes while Debian is designed to run 24/7. Moreover the number of packages
available, the number of architectures supported by Debian are far more greater
than that of Knoppix.
</p>
<p>
If you want Debian, it is best to install Debian from the get-go. Although it
is possible to install Debian through other distributions, such as Knoppix, the
procedure calls for expertise. If you are reading this FAQ, I would assume
that you are new to both Debian and Knoppix. In that case, save yourself a lot
of trouble later and install Debian right at the beginning.
</p>
<hr>
<h3><a name="s3.2.2"></a>3.2.2 I installed Knoppix/Linex/Ubuntu/... on my hard disk. Now I have a problem. What should I do?</h3>
<p>
You are advised not to use the Debian forums (either mailing lists or IRC) for
help as people might advise you thinking that you are running a Debian system
and the &quot;fixes&quot; they provide might not be suited to what you are
running. They might even worsen the problem you are facing.
</p>
<p>
Use the forums of the specific distribution you are using first. If you do not
get help or the help you get does not fix your problem you might want to try
asking in Debian forums, but keep the advise of the previous paragraph in mind.
</p>
<hr>
<h3><a name="s3.2.3"></a>3.2.3 I'm using Knoppix/Linex/Ubuntu/... and now I want to use Debian. How do I migrate?</h3>
<p>
Consider the change from a Debian-based distribution to Debian just like a
change from one operating system to another one. You should make a backup of
all your date and reinstall the operating system from scratch. You should not
attempt to &quot;upgrade&quot; to Debian using the package management tools as
you might end up with an unusable system.
</p>
<p>
If all your user data (i.e. your <code>/home</code>) is under a separate
partition migrating to Debian is actually quite simple, you just have to tell
the installation system to mount (but not reformat) that partition when
reinstalling. Making backups of your data, as well as your previous system's
configuration (i.e. <code>/etc/</code> and, maybe, <code>/var/</code>) is
still encouraged.

The Debian GNU/Linux FAQ
<br>Chapter 4 - Compatibility issues
</h1>
<hr>
<h2><a name="s-arches"></a>4.1 On what hardware architectures/systems does Debian GNU/Linux run?</h2>
<p>
Debian GNU/Linux includes complete source-code for all of the included
programs, so it should work on all systems which are supported by the Linux
kernel; see the <code><a
href="http://en.tldp.org/FAQ/Linux-FAQ/intro.html#DOES-LINUX-RUN-ON-MY-COMPUTER">Linux
FAQ</a></code> for details.
</p>
<p>
The current Debian GNU/Linux release, 4.0, contains a complete, binary
distribution for the following architectures:
</p>
<p>
<em>i386</em>: this covers systems based on Intel and compatible processors,
including Intel's 386, 486, Pentium, Pentium Pro, Pentium II (both Klamath and
Celeron), and Pentium III, and most compatible processors by AMD, Cyrix and
others.
</p>
<p>
<em>amd64</em>: this covers systems based on AMD 64bit CPUs with AMD64
extension and all Intel CPUs with EM64T extension, and a common 64bit
userspace.
</p>
<p>
<em>alpha</em>: Compaq/Digital's Alpha systems.
</p>
<p>
<em>sparc</em>: this covers Sun's SPARC and most UltraSPARC systems.
</p>
<p>
<em>powerpc</em>: this covers some IBM/Motorola PowerPC machines, including
CHRP, PowerMac and PReP machines.
</p>
<p>
<em>arm</em>: ARM and StrongARM machines.
</p>
<p>
<em>mips</em>: SGI's big-endian MIPS systems, Indy and Indigo2;
<em>mipsel</em>: little-endian MIPS machines, Digital DECstations.
</p>
<p>
<em>hppa</em>: Hewlett-Packard's PA-RISC machines (712, C3000, L2000, A500).
</p>
<p>
<em>ia64</em>: Intel IA-64 (&quot;Itanium&quot;) computers.
</p>
<p>
<em>s390</em>: IBM S/390 mainframe systems.
</p>
<p>
The development of binary distributions of Debian for Sparc64 (UltraSPARC
native) architectures is currently underway.
</p>
<p>
Support for the <em>m68k</em> architecture was dropped in this release, because
it did not meet the criteria set by the Debian Release Managers. This
architecture covers Amigas and ATARIs having a Motorola 680x0 processor for
x&gt;=2; with MMU. However, the port is still active and available for
installation even if not a part of this official stable release and might be
reactivated for future releases.
</p>
<p>
For more information on the available ports see the <code><a
href="http://www.debian.org/ports/">ports pages at the website</a></code>.
</p>
<p>
For further information on booting, partitioning your drive, enabling PCMCIA
(PC Card) devices and similar issues please follow the instructions given in
the Installation Manual, which is available from our WWW site at <code><a
href="http://www.debian.org/releases/stable/installmanual">http://www.debian.org/releases/stable/installmanual</a></code>.
</p>
<hr>
<h2><a name="s-otherdistribs"></a>4.2 How compatible is Debian with other distributions of Linux?</h2>
<p>
Debian developers communicate with other Linux distribution creators in an
effort to maintain binary compatibility across Linux distributions. Most
commercial Linux products run as well under Debian as they do on the system
upon which they were built.
</p>
<p>
Debian GNU/Linux adheres to the <code><a
href="http://www.pathname.com/fhs/">Linux Filesystem Hierarchy
Standard</a></code>. However, there is room for interpretation in some of the
rules within this standard, so there may be slight differences between a Debian
system and other Linux systems.
</p>
<p>
Debian GNU/Linux supports software developed for the <code><a
href="http://www.linuxbase.org/">Linux Standard Base</a></code>. The LSB is a
specification for allowing the same binary package to be used on multiple
distributions. The Debian Etch release is Certified for LSB Release 3.1, see
the <code><a
href="https://www.linux-foundation.org/lsb-cert/productdir.php">Linux
Foundation Certification webpage</a></code>. Discussion and coordination of
efforts towards ensuring Debian meets the requirements of the Linux Standard
Base is taking place on the <code><a
href="http://lists.debian.org/debian-lsb/">debian-lsb mailing list</a></code>.
</p>
<hr>
<h2><a name="s-otherunices"></a>4.3 How source code compatible is Debian with other Unix systems?</h2>
<p>
For most applications Linux source code is compatible with other Unix systems.
It supports almost everything that is available in System V Unix systems and
the free and commercial BSD-derived systems. However in the Unix business such
claim has nearly no value because there is no way to prove it. In the software
development area complete compatibility is required instead of compatibility in
&quot;about most&quot; cases. So years ago the need for standards arose, and
nowadays POSIX.1 (IEEE Standard 1003.1-1990) is one of the major standards for
source code compatibility in Unix-like operating systems.
</p>
<p>
Linux is intended to adhere to POSIX.1, but the POSIX standards cost real money
and the POSIX.1 (and FIPS 151-2) certification is quite expensive; this made it
more difficult for the Linux developers to work on complete POSIX conformance.
The certification costs make it unlikely that Debian will get an official
conformance certification even if it completely passed the validation suite.
(The validation suite is now freely available, so it is expected that more
people will work on POSIX.1 issues.)

Unifix GmbH (Braunschweig, Germany) developed a Linux system that has been
certified to conform to FIPS 151-2 (a superset of POSIX.1). This technology
was available in Unifix' own distribution called Unifix Linux 2.0 and in
Lasermoon's Linux-FT.

<h2><a name="s-otherpackages"></a>4.4 Can I use Debian packages (&quot;.deb&quot; files) on my Red Hat/Slackware/... Linux system? Can I use Red Hat packages (&quot;.rpm&quot; files) on my Debian GNU/Linux system?</h2>
<p>
Different Linux distributions use different package formats and different
package management programs.
</p>
<dl>
<dt><strong>You probably can:</strong></dt>
<dd>
<p>
A program to unpack a Debian package onto a Linux host that is been built from
a `foreign' distribution is available, and will generally work, in the sense
that files will be unpacked. The converse is probably also true, that is, a
program to unpack a Red Hat or Slackware package on a host that is based on
Debian GNU/Linux will probably succeed in unpacking the package and placing
most files in their intended directories. This is largely a consequence of the
existence (and broad adherence to) the Linux Filesystem Hierarchy Standard.
The <code><a href="http://packages.debian.org/alien">Alien</a></code> package
is used to convert between different package formats.
</p>
</dd>
</dl>
<dl>
<dt><strong>You probably do not want to:</strong></dt>
<dd>
<p>
Most package managers write administrative files when they are used to unpack
an archive. These administrative files are generally not standardized.
Therefore, the effect of unpacking a Debian package on a `foreign' host will
have unpredictable (certainly not useful) effects on the package manager on
that system. Likewise, utilities from other distributions might succeed in
unpacking their archives on Debian systems, but will probably cause the Debian
package management system to fail when the time comes to upgrade or remove some
packages, or even simply to report exactly what packages are present on a
system.
</p>
</dd>
</dl>
<dl>
<dt><strong>A better way:</strong></dt>
<dd>
<p>
The Linux File System Standard (and therefore Debian GNU/Linux) requires that
subdirectories under <samp>/usr/local/</samp> be entirely under the user's
discretion. Therefore, users can unpack `foreign' packages into this
directory, and then manage their configuration, upgrade and removal
individually.
</p>
</dd>
</dl>
<hr>
<h2><a name="s-non-debian-programs"></a>4.5 How should I install a non-Debian program?</h2>
<p>
Files under the directory <samp>/usr/local/</samp> are not under the control of
the Debian package management system. Therefore, it is good practice to place
the source code for your program in /usr/local/src/. For example, you might
extract the files for a package named &quot;foo.tar&quot; into the directory
<samp>/usr/local/src/foo</samp>. After you compile them, place the binaries in
<samp>/usr/local/bin/</samp>, the libraries in <samp>/usr/local/lib/</samp>,
and the configuration files in <samp>/usr/local/etc/</samp>.
</p>
<p>
If your programs and/or files really must be placed in some other directory,
you could still store them in <samp>/usr/local/</samp>, and build the
appropriate symbolic links from the required location to its location in
<samp>/usr/local/</samp>, e.g., you could make the link
</p>
<pre>
ln -s /usr/local/bin/foo /usr/bin/foo
</pre>
<p>
In any case, if you obtain a package whose copyright allows redistribution, you
should consider making a Debian package of it, and uploading it for the Debian
system. Guidelines for becoming a package developer are included in the Debian
Policy manual (see <a href="ch-support.en.html#s-debiandocs">What other
documentation exists on and for a Debian system?, Section 12.1</a>).
</p>
<hr>
<h2><a name="s-termcap"></a>4.6 Why can't I compile programs that require libtermcap?</h2>
<p>
Debian uses the <samp>terminfo</samp> database and the <samp>ncurses</samp>
library of terminal interface routes, rather than the <samp>termcap</samp>
database and the <samp>termcap</samp> library. Users who are compiling
programs that require some knowledge of the terminal interface should replace
references to <samp>libtermcap</samp> with references to
<samp>libncurses</samp>.
</p>
<p>
To support binaries that have already been linked with the <samp>termcap</samp>
library, and for which you do not have the source, Debian provides a package
called <code>termcap-compat</code>. This provides both
<samp>libtermcap.so.2</samp> and <samp>/etc/termcap</samp>. Install this
package if the program fails to run with the error message &quot;can't load
library 'libtermcap.so.2'&quot;, or complains about a missing
<samp>/etc/termcap</samp> file.
</p>
<hr>
<h2><a name="s-accelx"></a>4.7 Why can't I install AccelX?</h2>
<p>
AccelX uses the <samp>termcap</samp> library for installation. See <a
href="#s-termcap">Why can't I compile programs that require libtermcap?,
Section 4.6</a> above.
</p>
<hr>
<h2><a name="s-motifnls"></a>4.8 Why do my old XFree 2.1 Motif applications crash?</h2>
<p>
You need to install the <code>motifnls</code> package, which provides the
XFree-2.1 configuration files needed to allow Motif applications compiled under
XFree-2.1 to run under XFree-3.1.
</p>
<p>
Without these files, some Motif applications compiled on other machines (such
as Netscape) may crash when attempting to copy or paste from or to a text
field, and may also exhibit other problems.

<h1>
The Debian GNU/Linux FAQ
<br>Chapter 13 - Contributing to the Debian Project
</h1>
<hr>
<p>
<code><a href="http://www.debian.org/donations">Donations</a></code> of time
(to develop new packages, maintain existing packages, or provide user support),
resources (to mirror the FTP and WWW archives), and money (to pay for new
testbeds as well as hardware for the archives) can help the project.
</p>
<hr>
<h2><a name="s-contrib"></a>13.1 How can I become a Debian software developer?</h2>
<p>
The development of Debian is open to all, and new users with the right skills
and/or the willingness to learn are needed to maintain existing packages which
have been &quot;orphaned&quot; by their previous maintainers, to develop new
packages, and to provide user support.
</p>
<p>
The description of becoming a Debian developer can be found at the <code><a
href="http://www.debian.org/devel/join/newmaint">New Maintainer's
Corner</a></code> at the Debian web site.
</p>
<hr>
<h2><a name="s-contribresources"></a>13.2 How can I contribute resources to the Debian project?</h2>
<p>
Since the project aims to make a substantial body of software rapidly and
easily accessible throughout the globe, mirrors are urgently needed. It is
desirable but not absolutely necessary to mirror all of the archive. Please
visit the <code><a href="http://www.debian.org/mirror/size">Debian mirror
size</a></code> page for information on the disk space requirements.
</p>
<p>
Most of the mirroring is accomplished entirely automatically by scripts,
without any interaction. However, the occasional glitch or system change
occurs which requires human intervention.
</p>
<p>
If you have a high-speed connection to the Internet, the resources to mirror
all or part of the distribution, and are willing to take the time (or find
someone) who can provide regular maintenance of the system, then please contact
<code><a
href="mailto:debian-admin@lists.debian.org">debian-admin@lists.debian.org</a></code>.
</p>
<hr>
<h2><a name="s-supportingorganizations"></a>13.3 How can I contribute financially to the Debian project?</h2>
<p>
One can make individual donations to one of two organizations that are critical
to the development of the Debian project.
</p>
<hr>
<h3><a name="s-SPI"></a>13.3.1 Software in the Public Interest</h3>
<p>
Software in the Public Interest (SPI) is an IRS 501(c)(3) non-profit
organization, formed when FSF withdrew their sponsorship of Debian. The
purpose of the organization is to develop and distribute free software.
</p>
<p>
Our goals are very much like those of FSF, and we encourage programmers to use
the GNU General Public License on their programs. However, we have a slightly
different focus in that we are building and distributing a Linux system that
diverges in many technical details from the GNU system as originally planned by
FSF. We still communicate with FSF, and we cooperate in sending them changes
to GNU software and in asking our users to donate to FSF and the GNU project.
</p>
<p>
SPI can be reached at: <code><a
href="http://www.spi-inc.org/">http://www.spi-inc.org/</a></code>.
</p>
<hr>
<h3><a name="s-FSF"></a>13.3.2 Free Software Foundation</h3>
<p>
At this time there is no formal connection between Debian and the Free Software
Foundation. However, the Free Software Foundation is responsible for some of
the most important software components in Debian, including the GNU C compiler,
GNU Emacs, and much of the C run-time library that is used by all programs on
the system. FSF pioneered much of what free software is today: they wrote the
General Public License that is used on much of the Debian software, and they
invented the &quot;GNU&quot; project to create an entirely free Unix system.
Debian should be considered a descendent of the GNU system.
</p>
<p>
FSF can be reached at: <code><a
href="http://www.fsf.org/">http://www.fsf.org/</a></code>.

The Debian GNU/Linux FAQ
<br>Chapter 11 - Customizing your installation of Debian GNU/Linux
</h1>
<hr>
<h2><a name="s-papersize"></a>11.1 How can I ensure that all programs use the same paper size?</h2>
<p>
Install the <code>libpaper1</code> package, and it will ask you for a
system-wide default paper size. This setting will be kept in the file
<samp>/etc/papersize</samp>.
</p>
<p>
Users can override the paper size setting using the <samp>PAPERSIZE</samp>
environment variable. For details, see the manual page
<code>papersize(5)</code>.
</p>
<hr>
<h2><a name="s-hardwareaccess"></a>11.2 How can I provide access to hardware peripherals, without compromising security?</h2>
<p>
Many device files in the <samp>/dev</samp> directory belong to some predefined
groups. For example, <samp>/dev/fd0</samp> belongs to the <samp>floppy</samp>
group, and <samp>/dev/dsp</samp> belongs to the <samp>audio</samp> group.
</p>
<p>
If you want a certain user to have access to one of these devices, just add the
user to the group the device belongs to, i.e. do:
</p>
<pre>
adduser user group
</pre>
<p>
This way you won't have to change the file permissions on the device.
</p>
<p>
If you do this from within a user's shell or a GUI environment you have to
logout and login again to become an effective member of that group. To check
which groups you belong to run <samp>groups</samp>.
</p>
<p>
Notice that, since the introduction of <samp>udev</samp> if you change the
permissions of a hardware peripheral they might be be adjusted for some devices
when the system starts, if this happens to the hardware peripherals you are
instered in you will have to adjust the rules at <samp>/etc/udev</samp>.
</p>
<hr>
<h2><a name="s-consolefont"></a>11.3 How do I load a console font on startup the Debian way?</h2>
<p>
The <code>kbd</code> and <code>console-tools</code> packages support this, edit
<samp>/etc/kbd/config</samp> or <samp>/etc/console-tools/config</samp> files.
</p>
<hr>
<h2><a name="s-appdefaults"></a>11.4 How can I configure an X11 program's application defaults?</h2>
<p>
Debian's X programs will install their application resource data in the
<samp>/etc/X11/app-defaults/</samp> directory. If you want to customize X
applications globally, put your customizations in those files. They are marked
as configuration files, so their contents will be preserved during upgrades.
</p>
<hr>
<h2><a name="s-booting"></a>11.5 Every distribution seems to have a different boot-up method. Tell me about Debian's.</h2>
<p>
Like all Unices, Debian boots up by executing the program <samp>init</samp>.
The configuration file for <samp>init</samp> (which is
<samp>/etc/inittab</samp>) specifies that the first script to be executed
should be <samp>/etc/init.d/rcS</samp>. This script runs all of the scripts in
<samp>/etc/rcS.d/</samp> by sourcing or forking subprocess depending on their
file extension to perform initialization such as to check and to mount file
systems, to load modules, to start the network services, to set the clock, and
to perform other initialization. Then, for compatibility, it runs the files
(except those with a `.'in the filename) in <samp>/etc/rc.boot/</samp> too.
Any scripts in the latter directory are usually reserved for system
administrator use, and using them in packages is deprecated.
</p>
<p>
After completing the boot process, <samp>init</samp> executes all start scripts
in a directory specified by the default runlevel (this runlevel is given by the
entry for <samp>id</samp> in <samp>/etc/inittab</samp>). Like most System V
compatible Unices, Linux has 7 runlevels:
</p>
<ul>
<li>
<p>
0 (halt the system),
</p>
</li>
</ul>
<ul>
<li>
<p>
1 (single-user mode),
</p>
</li>
</ul>
<ul>
<li>
<p>
2 through 5 (various multi-user modes), and
</p>
</li>
</ul>
<ul>
<li>
<p>
6 (reboot the system).
</p>
</li>
</ul>
<p>
Debian systems come with id=2, which indicates that the default runlevel will
be '2' when the multi-user state is entered, and the scripts in
<samp>/etc/rc2.d/</samp> will be run.
</p>
<p>
In fact, the scripts in any of the directories, <samp>/etc/rcN.d/</samp> are
just symbolic links back to scripts in <samp>/etc/init.d/</samp>. However, the
<em>names</em> of the files in each of the <samp>/etc/rcN.d/</samp> directories
are selected to indicate the <em>way</em> the scripts in
<samp>/etc/init.d/</samp> will be run. Specifically, before entering any
runlevel, all the scripts beginning with 'K' are run; these scripts kill
services. Then all the scripts beginning with 'S' are run; these scripts start
services. The two-digit number following the 'K' or 'S' indicates the order in
which the script is run. Lower numbered scripts are executed first.
</p>
<p>
This approach works because the scripts in <samp>/etc/init.d/</samp> all take
an argument which can be either `start', `stop', `reload', `restart' or
`force-reload' and will then do the task indicated by the argument. These
scripts can be used even after a system has been booted, to control various
processes.
</p>
<p>
For example, with the argument `reload' the command
</p>
<pre>
/etc/init.d/sendmail reload
</pre>
<p>
sends the sendmail daemon a signal to reread its configuration file. (BTW,
Debian supplies <code>invoke-rc.d</code> as a wrapper for invoking the scripts
in <samp>/etc/init.d/</samp>.)
</p>
<hr>
<h2><a name="s-custombootscripts"></a>11.6 It looks as if Debian does not use <samp>rc.local</samp> to customize the boot process; what facilities are provided?</h2>
<p>
Suppose a system needs to execute script <samp>foo</samp> on start-up, or on
entry to a particular (System V) runlevel. Then the system administrator
should:
</p>
<ul>
<li>
<p>
Enter the script <samp>foo</samp> into the directory <samp>/etc/init.d/</samp>.
</p>
</li>
</ul>
<ul>
<li>
<p>
Run the Debian command <samp>update-rc.d</samp> with appropriate arguments, to
specify which runlevels should start the service, and which runlevels should
stop the service.
</p>
</li>
</ul>
<ul>
<li>
<p>
Consider rebooting the system to check that the service starts correctly
(assuming that you've asked for it to be started in the default runlevel).
Otherwise, manually start it by running `<samp>/etc/init.d/foo start</samp>'.
</p>
</li>
</ul>
<p>
One might, for example, cause the script <samp>foo</samp> to execute at
boot-up, by putting it in <samp>/etc/init.d/</samp> and running
<samp>update-rc.d foo defaults 19</samp>. The argument `<samp>defaults</samp>'
refers to the default runlevels, which means (at least in absence of any LSB
comment block to the contrary) to start the service in runlevels 2 through 5,
and to stop the service in runlevels 0, 1 and 6. (Any LSB Default-Start and
Default-Stop directives in <samp>foo</samp> take precedence when using the
sysv-rc version of update-rc.d, but are ignored by the current (v0.8.10)
file-rc version of update-rc.d.) The argument `<samp>19</samp>' ensures that
<samp>foo</samp> is called after all scripts whose number is less than 19 have
completed, and before all scripts whose number is 20 or greater.
</p>
<hr>
<h2><a name="s-interconffiles"></a>11.7 How does the package management system deal with packages that contain configuration files for other packages?</h2>
<p>
Some users wish to create, for example, a new server by installing a group of
Debian packages and a locally generated package consisting of configuration
files. This is not generally a good idea, because <code>dpkg</code> will not
know about those configuration files if they are in a different package, and
may write conflicting configurations when one of the initial &quot;group&quot;
of packages is upgraded.
</p>
<p>
Instead, create a local package that modifies the configuration files of the
&quot;group&quot; of Debian packages of interest. Then <code>dpkg</code> and
the rest of the package management system will see that the files have been
modified by the local &quot;sysadmin&quot; and will not try to overwrite them
when those packages are upgraded.
</p>
<hr>
<h2><a name="s-divert"></a>11.8 How do I override a file installed by a package, so that a different version can be used instead?</h2>
<p>
Suppose a sysadmin or local user wishes to use a program
&quot;login-local&quot; rather than the program &quot;login&quot; provided by
the Debian <code>login</code> package.
</p>
<p>
Do <strong>not</strong>:
</p>
<ul>
<li>
<p>
Overwrite <samp>/bin/login</samp> with <samp>login-local</samp>.
</p>
</li>
</ul>
<p>
The package management system will not know about this change, and will simply
overwrite your custom <samp>/bin/login</samp> whenever <samp>login</samp> (or
any package that provides <samp>/bin/login</samp>) is installed or updated.
</p>
<p>
Rather, do
</p>
<ul>
<li>
<p>
Execute:
</p>
<pre>
dpkg-divert --divert /bin/login.debian /bin/login
</pre>
<p>
in order to cause all future installations of the Debian <code>login</code>
package to write the file <samp>/bin/login</samp> to
<samp>/bin/login.debian</samp> instead.
</p>
</li>
</ul>
<ul>
<li>
<p>
Then execute:
</p>
<pre>
cp login-local /bin/login
</pre>
<p>
to move your own locally-built program into place.
</p>
</li>
</ul>
<p>
Run <samp>dpkg-divert --list</samp> to see which diversions are currently
active on your system.
</p>
<p>
Details are given in the manual page <code>dpkg-divert(8)</code>.
</p>
<hr>
<h2><a name="s-localpackages"></a>11.9 How can I have my locally-built package included in the list of available packages that the package management system knows about?</h2>
<p>
Execute the command:
</p>
<pre>
dpkg-scanpackages BIN_DIR OVERRIDE_FILE [PATHPREFIX] &gt; my_Packages
</pre>
<p>
where:
</p>
<ul>
<li>
<p>
BIN-DIR is a directory where Debian archive files (which usually have an
extension of &quot;.deb&quot;) are stored.
</p>
</li>
</ul>
<ul>
<li>
<p>
OVERRIDE_FILE is a file that is edited by the distribution maintainers and is
usually stored on a Debian FTP archive at <samp>indices/override.main.gz</samp>
for the Debian packages in the &quot;main&quot; distribution. You can ignore
this for local packages.
</p>
</li>
</ul>
<ul>
<li>
<p>
PATHPREFIX is an <em>optional</em> string that can be prepended to the
<samp>my_Packages</samp> file being produced.
</p>
</li>
</ul>
<p>
Once you have built the file <samp>my_Packages</samp>, tell the package
management system about it by using the command:
</p>
<pre>
dpkg --merge-avail my_Packages
</pre>
<p>
If you are using APT, you can add the local repository to your
<code>sources.list(5)</code> file, too.
</p>
<hr>
<h2><a name="s-diverse"></a>11.10 Some users like mawk, others like gawk; some like vim, others like elvis; some like trn, others like tin; how does Debian support diversity?</h2>
<p>
There are several cases where two packages provide two different versions of a
program, both of which provide the same core functionality. Users might prefer
one over another out of habit, or because the user interface of one package is
somehow more pleasing than the interface of another. Other users on the same
system might make a different choice.
</p>
<p>
Debian uses a &quot;virtual&quot; package system to allow system administrators
to choose (or let users choose) their favorite tools when there are two or more
that provide the same basic functionality, yet satisfy package dependency
requirements without specifying a particular package.
</p>
<p>
For example, there might exist two different versions of newsreaders on a
system. The news server package might 'recommend' that there exist
<em>some</em> news reader on the system, but the choice of <samp>tin</samp> or
<samp>trn</samp> is left up to the individual user. This is satisfied by
having both the <code>tin</code> and <code>trn</code> packages provide the
virtual package <code>news-reader</code>. <em>Which</em> program is invoked is
determined by a link pointing from a file with the virtual package name
<samp>/etc/alternatives/news-reader</samp> to the selected file, e.g.,
<samp>/usr/bin/trn</samp>.
</p>
<p>
A single link is insufficient to support full use of an alternate program;
normally, manual pages, and possibly other supporting files must be selected as
well. The Perl script <samp>update-alternatives</samp> provides a way of
ensuring that all the files associated with a specified package are selected as
a system default.
</p>
<p>
For example, to check what executables provide `x-window-manager', run:
</p>
<pre>
update-alternatives --display x-window-manager
</pre>
<p>
If you want to change it, run:
</p>
<pre>
update-alternatives --config x-window-manager
</pre>
<p>
And follow the instructions on the screen (basically, press the number next to
the entry you'd like better).
</p>
<p>
If a package doesn't register itself as a window manager for some reason (file
a bug if it's in error), or if you use a window manager from /usr/local
directory, the selections on screen won't contain your preferred entry. You
can update the link through command line options, like this:
</p>
<pre>
update-alternatives --install /usr/bin/x-window-manager \
x-window-manager /usr/local/bin/wmaker-cvs 50
</pre>
<p>
The first argument to `--install' option is the symlink that points to
/etc/alternatives/NAME, where NAME is the second argument. The third argument
is the program to which /etc/alternatives/NAME should point to, and the fourth
argument is the priority (larger value means the alternative will more probably
get picked automatically).
</p>
<p>
To remove an alternative you added, simply run:
</p>
<pre>
update-alternatives --remove x-window-manager /usr/local/bin/wmaker-cvs
</pre>

</h1>

<h2><a name="s-authors"></a>16.1 Authors</h2>
<p>
The first edition of this FAQ was made and maintained by J.H.M. Dassen (Ray)
and Chuck Stickelman. Authors of the rewritten Debian GNU/Linux FAQ are Susan
G. Kleinmann and Sven Rudolph. After them, the FAQ was maintained by Santiago
Vila and, later, by Josip Rodin. The current maintainer is Javier
Fernandez-Sanguino.

<hr>
<h2><a name="s-dists"></a>6.1 How many Debian distributions are there?</h2>
<p>
There are three major distributions: the &quot;stable&quot; distribution, the
&quot;testing&quot; distribution, and the &quot;unstable&quot; distribution.
The &quot;testing&quot; distribution is sometimes `frozen' (see <a
href="#s-frozen">What about &quot;testing&quot;? How is it `frozen'?, Section
6.5.1</a>). Next to these, there is the &quot;oldstable&quot; distribution
(that's just the one from before &quot;stable&quot;), and the
&quot;experimental&quot; distribution.
</p>
<p>
Experimental is used for packages which are still being developed, and with a
high risk of breaking your system. It's used by developers who'd like to study
and test bleeding edge software. Users shouldn't be using packages from here,
because they can be dangerous and harmful even for the most experienced people.
</p>
<p>
See <a href="ch-choosing.en.html">Choosing a Debian distribution, Chapter 3</a>
for help when choosing a Debian distribution.
</p>
<hr>
<h2><a name="s-codenames"></a>6.2 What are all those names like etch, lenny, etc.?</h2>
<p>
They are just &quot;codenames&quot;. When a Debian distribution is in the
development stage, it has no version number but a codename. The purpose of
these codenames is to make easier the mirroring of the Debian distributions (if
a real directory like <samp>unstable</samp> suddenly changed its name to
<samp>stable</samp>, a lot of stuff would have to be needlessly downloaded
again).
</p>
<p>
Currently, <samp>stable</samp> is a symbolic link to <samp>etch</samp> (i.e.
Debian GNU/Linux 4.0) and <samp>testing</samp> is a symbolic link to
<samp>lenny</samp>. This means that <samp>etch</samp> is the current stable
distribution and <samp>lenny</samp> is the current testing distribution.
</p>
<p>
<samp>unstable</samp> is a permanent symbolic link to <samp>sid</samp>, as
<samp>sid</samp> is always the unstable distribution (see <a href="#s-sid">What
about &quot;sid&quot;?, Section 6.3</a>).
</p>
<hr>
<h3><a name="s-oldcodenames"></a>6.2.1 Which other codenames have been used in the past?</h3>
<p>
Other codenames that have been already used are: <samp>buzz</samp> for release
1.1, <samp>rex</samp> for release 1.2, <samp>bo</samp> for releases 1.3.x,
<samp>hamm</samp> for release 2.0, <samp>slink</samp> for release 2.1,
<samp>potato</samp> for release 2.2, <samp>woody</samp> for release 3.0,
<samp>sarge</samp> for release 3.1, and <samp>etch</samp> for release 4.0.
</p>
<hr>
<h3><a name="s-sourceforcodenames"></a>6.2.2 Where do these codenames come from?</h3>
<p>
So far they have been characters taken from the movie &quot;Toy Story&quot; by
Pixar.
</p>
<ul>
<li>
<p>
<em>buzz</em> (Buzz Lightyear) was the spaceman,
</p>
</li>
</ul>
<ul>
<li>
<p>
<em>rex</em> was the tyrannosaurus,
</p>
</li>
</ul>
<ul>
<li>
<p>
<em>bo</em> (Bo Peep) was the girl who took care of the sheep,
</p>
</li>
</ul>
<ul>
<li>
<p>
<em>hamm</em> was the piggy bank,
</p>
</li>
</ul>
<ul>
<li>
<p>
<em>slink</em> (Slinky Dog (R)) was the toy dog,
</p>
</li>
</ul>
<ul>
<li>
<p>
<em>potato</em> was, of course, Mr. Potato (R),
</p>
</li>
</ul>
<ul>
<li>
<p>
<em>woody</em> was the cowboy,
</p>
</li>
</ul>
<ul>
<li>
<p>
<em>sarge</em> was the sergeant of the Green Plastic Army Men,
</p>
</li>
</ul>
<ul>
<li>
<p>
<em>etch</em> was the toy blackboard (Etch-a-Sketch (R)),
</p>
</li>
</ul>
<ul>
<li>
<p>
<em>lenny</em> was the binoculars.
</p>
</li>
</ul>
<ul>
<li>
<p>
<em>sid</em> was the boy next door who destroyed toys.
</p>
</li>
</ul>
<hr>
<h2><a name="s-sid"></a>6.3 What about &quot;sid&quot;?</h2>
<p>
<em>sid</em> or <em>unstable</em> is the place where most of the packages are
initially uploaded. It will never be released directly, because packages which
are to be released will first have to be included in <em>testing</em>, in order
to be released in <em>stable</em> later on. sid contains packages for both
released and unreleased architectures.
</p>
<p>
The name &quot;sid&quot; also comes from the &quot;Toy Story&quot; animated
motion picture: Sid was the boy next door who destroyed toys :-)
</p>
<p>
[<a href="footnotes.en.html#f2" name="fr2">2</a>]
</p>
<hr>
<h2><a name="s-stable"></a>6.4 What does the stable directory contain?</h2>
<ul>
<li>
<p>
stable/main/: This directory contains the packages which formally constitute
the most recent release of the Debian GNU/Linux system.
</p>
<p>
These packages all comply with the <code><a
href="http://www.debian.org/social_contract#guidelines">Debian Free Software
Guidelines</a></code>, and are all freely usable and distributable.
</p>
</li>
</ul>
<ul>
<li>
<p>
stable/non-free/: This directory contains packages distribution of which is
restricted in a way that requires that distributors take careful account of the
specified copyright requirements.
</p>
<p>
For example, some packages have licenses which prohibit commercial
distribution. Others can be redistributed but are in fact shareware and not
free software. The licenses of each of these packages must be studied, and
possibly negotiated, before the packages are included in any redistribution
(e.g., in a CD-ROM).
</p>
</li>
</ul>
<ul>
<li>
<p>
stable/contrib/: This directory contains packages which are DFSG-free and
<em>freely distributable</em> themselves, but somehow depend on a package that
is <em>not</em> freely distributable and thus available only in the non-free
section.
</p>
</li>
</ul>
<hr>
<h2><a name="s-testing"></a>6.5 What does the testing distribution contain?</h2>
<p>
Packages are installed into the `testing' directory after they have undergone
some degree of testing in <a href="#s-unstable">unstable</a>.
</p>
<p>
They must be in sync on all architectures where they have been built and
mustn't have dependencies that make them uninstallable; they also have to have
fewer release-critical bugs than the versions currently in testing. This way,
we hope that `testing' is always close to being a release candidate.
</p>
<p>
More information about the status of &quot;testing&quot; in general and the
individual packages is available at <code><a
href="http://www.debian.org/devel/testing">http://www.debian.org/devel/testing</a></code>.
</p>
<hr>
<h3><a name="s-frozen"></a>6.5.1 What about &quot;testing&quot;? How is it `frozen'?</h3>
<p>
When the &quot;testing&quot; distribution is mature enough, the release manager
starts `freezing' it. The normal propagation delays are increased to ensure
that as little as possible new bugs from &quot;unstable&quot; enter
&quot;testing&quot;.
</p>
<p>
After a while, the &quot;testing&quot; distribution becomes truly `frozen'.
This means that all new packages that are to propagate to the
&quot;testing&quot; are held back, unless they include release-critical bug
fixes. The &quot;testing&quot; distribution can also remain in such a deep
freeze during the so-called `test cycles', when the release is imminent.
</p>
<p>
We keep a record of bugs in the &quot;testing&quot; distribution that can hold
off a package from being released, or bugs that can hold back the whole
release. For details, please see <code><a
href="http://www.debian.org/releases/testing/">current testing release
information</a></code>.
</p>
<p>
Once that bug count lowers to maximum acceptable values, the frozen
&quot;testing&quot; distribution is declared &quot;stable&quot; and released
with a version number.
</p>
<p>
With each new release, the previous &quot;stable&quot; distribution becomes
obsolete and moves to the archive. For more information please see <code><a
href="http://www.debian.org/distrib/archive">Debian archive</a></code>.
</p>
<hr>
<h2><a name="s-unstable"></a>6.6 What does the unstable distribution contain?</h2>
<p>
The `unstable' directory contains a snapshot of the current development system.
Users are welcome to use and test these packages, but are warned about their
state of readiness. The advantage of using the unstable distribution is that
you are always up-to-date with the latest in GNU/Linux software industry, but
if it breaks: you get to keep both parts :-)
</p>
<p>
There are also main, contrib and non-free subdirectories in `unstable',
separated on the same criteria as in `stable'.
</p>
<hr>
<h2><a name="s-dirtree"></a>6.7 What are all those directories at the Debian FTP archives?</h2>
<p>
The software that has been packaged for Debian GNU/Linux is available in one of
several directory trees on each Debian mirror site.
</p>
<p>
The <samp>dists</samp> directory is short for &quot;distributions&quot;, and it
is the canonical way to access the currently available Debian releases (and
pre-releases).
</p>
<p>
The <samp>pool</samp> directory contains the actual packages, see <a
href="#s-pools">What's in the <samp>pool</samp> directory?, Section 6.10</a>.
</p>
<p>
There are the following supplementary directories:
</p>
<dl>
<dt><em>/tools/</em>:</dt>
<dd>
<p>
DOS utilities for creating boot disks, partitioning your disk drive,
compressing/decompressing files, and booting Linux.
</p>
</dd>
</dl>
<dl>
<dt><em>/doc/</em>:</dt>
<dd>
<p>
The basic Debian documentation, such as this FAQ, the bug reporting system
instructions, etc.
</p>
</dd>
</dl>
<dl>
<dt><em>/indices/</em>:</dt>
<dd>
<p>
various indices of the site (the Maintainers file and the override files).
</p>
</dd>
</dl>
<dl>
<dt><em>/project/</em>:</dt>
<dd>
<p>
mostly developer-only materials and some miscellaneous files.
</p>
</dd>
</dl>
<hr>
<h2><a name="s-archsections"></a>6.8 What are all those directories inside <samp>dists/stable/main</samp>?</h2>
<p>
Within each of the major directory trees[<a href="footnotes.en.html#f3"
name="fr3">3</a>], there are three sets of subdirectories containing index
files.
</p>
<p>
There's one set of <samp>binary-<var>something</var></samp> subdirectories
which contain index files for binary packages of each available computer
architecture, for example <samp>binary-i386</samp> for packages which execute
on Intel x86 PC machines or <samp>binary-sparc</samp> for packages which
execute on Sun SPARCStations.
</p>
<p>
The complete list of available architectures for each release is available at
<code><a href="http://www.debian.org/releases/">the release's web
page</a></code>. For the current release, please see <a
href="ch-compat.en.html#s-arches">On what hardware architectures/systems does
Debian GNU/Linux run?, Section 4.1</a>.
</p>
<p>
The index files in binary-* are called Packages(.gz, .bz2) and they include a
summary of each binary package that is included in that distribution. The
actual binary packages reside in the top level <a
href="#s-pools"><samp>pool</samp> directory</a>.
</p>
<p>
Furthermore, there's a subdirectory called source/ which contains index files
for source packages included in the distribution. The index file is called
Sources(.gz, .bz2).
</p>
<p>
Last but not least, there's a set of subdirectories meant for the installation
system index files, they are at
<samp>debian-installer/binary-<var>architecture</var></samp>.
</p>
<hr>
<h2><a name="s-source"></a>6.9 Where is the source code?</h2>
<p>
Source code is included for everything in the Debian system. Moreover, the
license terms of most programs in the system <em>require</em> that source code
be distributed along with the programs, or that an offer to provide the source
code accompany the programs.
</p>
<p>
The source code is distributed in the <samp>pool</samp> directory (see <a
href="#s-pools">What's in the <samp>pool</samp> directory?, Section 6.10</a>)
together with all the architecture-specific binary directories. To retrieve
the source code without having to be familiar with the structure of the FTP
archive, try a command like <samp>apt-get source mypackagename</samp>.
</p>
<p>
Some packages are only distributed as source code due to the restrictions in
their licenses. Notably, one such package is <samp>pine</samp>, see <a
href="ch-software.en.html#s-pine">Where is pine?, Section 5.10</a> for more
information.
</p>
<p>
Source code may or may not be available for packages in the &quot;contrib&quot;
and &quot;non-free&quot; directories, which are not formally part of the Debian
system.
</p>
<hr>
<h2><a name="s-pools"></a>6.10 What's in the <samp>pool</samp> directory?</h2>
<p>
Packages are kept in a large `pool', structured according to the name of the
source package. To make this manageable, the pool is subdivided by section
(`main', `contrib' and `non-free') and by the first letter of the source
package name. These directories contain several files: the binary packages for
each architecture, and the source packages from which the binary packages were
generated.
</p>
<p>
You can find out where each package is placed by executing a command like
<samp>apt-cache showsrc mypackagename</samp> and looking at the `Directory:'
line. For example, the <samp>apache</samp> packages are stored in
<samp>pool/main/a/apache/</samp>.
</p>
<p>
Additionally, since there are so many <samp>lib*</samp> packages, these are
treated specially: for instance, libpaper packages are stored in
<samp>pool/main/libp/libpaper/</samp>.
</p>
<p>
[<a href="footnotes.en.html#f4" name="fr4">4</a>]
</p>
<hr>
<h2><a name="s-incoming"></a>6.11 What is &quot;incoming&quot;?</h2>
<p>
After a developer uploads a package, it stays for a short while in the
&quot;incoming&quot; directory before it is checked that it's genuine and
allowed into the archive.
</p>
<p>
Usually nobody should install things from this place. However, in some rare
cases of emergency, the incoming directory is available at <code><a
href="http://incoming.debian.org/">http://incoming.debian.org/</a></code>. You
can manually fetch packages, check the GPG signature and MD5sums in the
.changes and .dsc files, and then install them.
</p>
<hr>
<h2><a name="s-ownrepository"></a>6.12 How do I set up my own apt-able repository?</h2>
<p>
If you have built some private Debian packages which you'd like to install
using the standard Debian package management tools, you can set up your own
apt-able package archive. This is also useful if you'd like to share your
Debian packages while these are not distributed by the Debian project.
Instructions on how to do this are given in the <code><a
href="http://www.debian.org/doc/manuals/repository-howto/repository-howto">Debian
Repository HOWTO</a></code>.

The Debian GNU/Linux FAQ
<br>Chapter 2 - Getting and installing Debian GNU/Linux
</h1>
<hr>
<p>
The official document giving installation instructions is the <code><a
href="http://www.debian.org/releases/stable/installmanual">Debian GNU/Linux
Installation Guide</a></code>. We'll give some additional notes about getting
and installing Debian GNU/Linux here.
</p>
<hr>
<h2><a name="s-version"></a>2.1 What is the latest version of Debian?</h2>
<p>
Currently there are three versions of Debian GNU/Linux:
</p>
<dl>
<dt><em>release 4.0, a.k.a. the `stable' distribution or etch</em></dt>
<dd>
<p>
This is stable and well tested software, it changes if major security or
usability fixes are incorporated.
</p>
</dd>
</dl>
<dl>
<dt><em>the `testing' distribution, currently called lenny</em></dt>
<dd>
<p>
This is where packages that will be released as the next `stable' are placed;
they've had some testing in unstable but they may not be completely fit for
release yet. This distribution is updated more often than `stable', but not
more often than `unstable'.
</p>
</dd>
</dl>
<dl>
<dt><em>the `unstable' distribution</em></dt>
<dd>
<p>
This is the version currently under development; it is updated continuously.
You can retrieve packages from the `unstable' archive on any Debian FTP site
and use them to upgrade your system at any time, but you may not expect the
system to be as usable or as stable as before - that's why it's called
`<strong>unstable</strong>'!
</p>
</dd>
</dl>
<p>
Please see <a href="ch-ftparchives.en.html#s-dists">How many Debian
distributions are there?, Section 6.1</a> for more information.
</p>
<hr>
<h2><a name="s-updatestable"></a>2.2 Are there package upgrades in `stable'?</h2>
<p>
No new functionality is added to the stable release. Once a Debian version is
released and tagged `stable' it will only get security updates. That is, only
packages for which a security vulnerability has been found after the release
will be upgraded. All the security updates are served through <code><a
href="ftp://security.debian.org">security.debian.org</a></code>.
</p>
<p>
Security updates serve one purpose: to supply a fix for a security
vulnerability. They are not a method for sneaking additional changes into the
stable release without going through normal point release procedure.
Consequently, fixes for packages with security issues will not upgrade the
software. The Debian Security Team will backport the necessary fixes to the
version of the software distributed in `stable' instead.
</p>
<p>
For more information related to security support please read the <code><a
href="http://www.debian.org/security/faq">Security FAQ</a></code> or the
<code><a href="http://www.debian.org/doc/manuals/securing-debian-howto/">Debian
Security Manual</a></code>.
</p>
<hr>
<h2><a name="s-boot-floppies"></a>2.3 Where/how can I get the Debian installation disks?</h2>
<p>
You can get the installation disks by downloading the appropriate files from
one of the <code><a href="http://www.debian.org/mirror/list">Debian
mirrors</a></code>.
</p>
<p>
Please refer to <code><a href="http://www.debian.org/CD">Debian GNU/Linux on
CDs</a></code> for more information about CD (and DVD) images.
</p>
<hr>
<h2><a name="s-cdrom"></a>2.4 How do I install the Debian from CD-ROMs?</h2>
<p>
Installing Debian from CD is straightforward: configure your system for booting
off a CD, insert your CD, and reboot. Your system will now be running the
Debian Installer. See the <code><a
href="http://www.debian.org/releases/stable/installmanual">Debian GNU/Linux
Installation Guide</a></code> for more information.
</p>
<hr>
<h2><a name="s-cdimage-symlinks"></a>2.5 Why does the official stable released CD-ROM contain symlinks for `frozen' and `unstable'? I thought this CD contains just `stable'!</h2>
<p>
Official Debian CD images indeed contain symlinks like:
</p>
<pre>
/dists/frozen -&gt; etch/
/dists/stable -&gt; etch/
/dists/testing -&gt; etch/
/dists/unstable -&gt; etch/
</pre>
<p>
so that they work when your sources.list has an entry like
</p>
<pre>
deb cdrom:[&lt;name as on cd label&gt;]/ unstable main [...]
</pre>
<p>
.
</p>
<p>
The fact these symlinks are present does <em>not</em> mean the image is
`unstable' or `testing' or anything. Read the CD label in
<code>/.disk/info</code> to find out which Debian version it contains. This
information is also present in <code>/README.txt</code> on the CD.
</p>
<p>
Read <code><a
href="http://www.debian.org/releases/">http://www.debian.org/releases/</a></code>
to find out what the current `stable' and `testing' releases are.

<h2><a name="s-remoteinstall"></a>2.6 Can I get and install Debian directly from a remote Internet site?</h2>
<p>
Yes. You can boot the Debian installation system from a set of files you can
download from our FTP site and its mirrors.
</p>
<p>
You can download a small CD image file, create a bootable CD from it, install
the basic system from it and the rest over the network. For more information
please see <code><a
href="http://www.debian.org/CD/netinst/">http://www.debian.org/CD/netinst/</a></code>.
</p>
<p>
You can also download even smaller floppy disk image files, create bootable
diskettes from them, start the installation procedure and get the rest of
Debian over the network.
</p>
<hr>
<h2><a name="s-alternativebootinstaller"></a>2.7 Are there any alternative strategies for booting the system installer?</h2>
<p>
Yes. Apart from CD or DVD, you can install Debian GNU/Linux by booting from
floppy disks, USB memory stick, directly from hard disk, or using TFTP net
booting. For installing on multiple computers it's possible to do fully
automatic installations. NB: not all methods are supported by all computer
architectures. Once the installer has booted, the rest of the system can be
downloaded over the network, or installed from local media. See the <code><a
href="http://www.debian.org/releases/stable/installmanual">Debian GNU/Linux
Installation Guide</a></code> for more information.

<h1>
The Debian GNU/Linux FAQ
<br>Chapter 10 - Debian and the kernel
</h1>
<hr>
<h2><a name="s-non-debian-kernel"></a>10.1 Can I install and compile a kernel without some Debian-specific tweaking?</h2>
<p>
Yes.
</p>
<p>
There's only one common catch: the Debian C libraries are built with the most
recent <em>stable</em> releases of the <strong>kernel</strong> headers. If you
happen to need to compile a program with kernel headers newer than the ones
from the stable branch, then you should either upgrade the package containing
the headers (<code>libc6-dev</code>), or use the new headers from an unpacked
tree of the newer kernel. That is, if the kernel sources are in
<code>/usr/src/linux</code>, then you should add
<samp>-I/usr/src/linux/include/</samp> to your command line when compiling.
</p>
<hr>
<h2><a name="s-customkernel"></a>10.2 What tools does Debian provide to build custom kernels?</h2>
<p>
Users who wish to (or must) build a custom kernel are encouraged to download
the package <code>kernel-package</code>. This package contains the script to
build the kernel package, and provides the capability to create a Debian
<code>linux-image-<var>version</var></code> package just by running the command
</p>
<pre>
make-kpkg --initrd kernel_image
</pre>
<p>
in the top-level kernel source directory. Help is available by executing the
command
</p>
<pre>
make-kpkg --help
</pre>
<p>
and through the manual page <code>make-kpkg(1)</code>.
</p>
<p>
Users must separately download the source code for the most recent kernel (or
the kernel of their choice) from their favorite Linux archive site, unless a
<code>linux-source-<var>version</var></code> package is available (where
<var>version</var> stands for the kernel version).
</p>
<p>
Detailed instructions for using the <code>kernel-package</code> package are
given in the file <code>/usr/share/doc/kernel-package/README.gz</code>.
</p>
<hr>
<h2><a name="s-custombootdisk"></a>10.3 How can I make a custom boot floppy?</h2>
<p>
This task is greatly aided by the Debian package <code>boot-floppies</code>,
normally found in the <samp>admin</samp> section of the Debian FTP archive.
Shell scripts in this package produce boot floppies in the
<samp>SYSLINUX</samp> format. These are <samp>MS-DOS</samp> formatted floppies
whose master boot records have been altered so that they boot Linux directly
(or whatever other operating system has been defined in the
<code>syslinux.cfg</code> file on the floppy). Other scripts in this package
produce emergency root disks and can even reproduce the base disks.
</p>
<p>
You will find more information about this in the
<code>/usr/share/doc/boot-floppies/README</code> file after installing the
<code>boot-floppies</code> package.
</p>
<hr>
<h2><a name="s-modules"></a>10.4 What special provisions does Debian provide to deal with modules?</h2>
<p>
Debian's <code>modconf</code> package provides a shell script
(<code>/usr/sbin/modconf</code>) which can be used to customize the
configuration of modules. This script presents a menu-based interface,
prompting the user for particulars on the loadable device drivers in his
system. The responses are used to customize the file
<code>/etc/modules.conf</code> (which lists aliases, and other arguments that
must be used in conjunction with various modules) through files in
<code>/etc/modutils/</code>, and <code>/etc/modules</code> (which lists the
modules that must be loaded at boot time).
</p>
<p>
Like the (new) <code>Configure.help</code> files that are now available to
support the construction of custom kernels, the <code>modconf</code> package
comes with a series of help files (in <code>/usr/lib/modules_help/</code>)
which provide detailed information on appropriate arguments for each of the
modules.
</p>
<hr>
<h2><a name="s-removeoldkernel"></a>10.5 Can I safely de-install an old kernel package, and if so, how?</h2>
<p>
Yes. The <code>linux-image-<var>NNN</var>.prerm</code> script checks to see
whether the kernel you are currently running is the same as the kernel you are
trying to de-install. Therefore you can remove unwanted kernel image packages
using this command:
</p>
<pre>
dpkg --purge linux-image-<var>NNN</var>
</pre>
<p>
(replace <var>NNN</var> with your kernel version and revision number, of
course)
</p>

<h1>
The Debian GNU/Linux FAQ
<br>Chapter 15 - Changes expected in the next major release of Debian
</h1>
<hr>
<h2><a name="s-i18n"></a>15.1 Extended support for non-English users</h2>
<p>
Debian already has very good support for non-English users, see <a
href="ch-software.en.html#s-nonenglish">How does Debian support non-English
languages?, Section 5.9</a>.
</p>
<p>
We hope to find people who will provide support for even more languages, and
translate. Some programs already support internationalization, so we need
message catalogs translators. Many programs still remain to be properly
internationalized.
</p>
<p>
The GNU Translation Project <code><a
href="ftp://ftp.gnu.org/pub/gnu/ABOUT-NLS">ftp://ftp.gnu.org/pub/gnu/ABOUT-NLS</a></code>
works on internationalizing the GNU programs.
</p>
<p>
Specifically for Debian lenny, we're working on things like the following:
</p>
<ul>
<li>
<p>
I18n support in all debconf-using packages: Packages using the Debian
configuration management must allow for translation of all messages displayed
to the user during package configuration.
</p>
</li>
</ul>
<ul>
<li>
<p>
I18n support for package descriptions: Update package management frontends to
use the translated descriptions of packages.
</p>
</li>
</ul>
<ul>
<li>
<p>
UTF-8 debian/changelog and debian/control. This way, e.g. names of people
from asian countries can get typeset the right way in changelogs.
</p>
</li>
</ul>
<hr>
<h2><a name="s-dependencybasedboot"></a>15.2 Faster booting: Dependency based boot sequence</h2>
<p>
Work is being done on <code><a
href="http://wiki.debian.org/LSBInitScripts/DependencyBasedBoot">converting the
Debian boot sequence</a></code> to use dynamic and dependency based ordering
instead of hardcoded sequence numbers. Once that's finished, Debian systems
will boot much faster.
</p>
<hr>
<h2><a name="s-di"></a>15.3 Improvements in the Debian Installer</h2>
<p>
Lots of work has been done on the Debian Installer, resulting in major
improvements. We'll mention just two of them here.
</p>
<p>
Starting the installer from Microsoft Windows: It is now possible to start the
installer directly from Microsoft Windows without the need to change BIOS
settings. Upon insertion of a CD-ROM, DVD-ROM or USB stick, an autorun program
will be started, offering a step-by-step process to start the Debian Installer.
</p>
<p>
The debian-installer now includes experimental support for installing Debian on
systems with Serial ATA RAID.
</p>
<hr>
<h2><a name="s-morearches"></a>15.4 More architectures</h2>
<p>
Complete Debian system on other architectures such as <code><a
href="http://wiki.debian.org/ArmEabiPort">ARM EABI</a></code> (referred to as
&quot;armel&quot;) (next to the old &quot;arm&quot;) will likely get supported
with lenny. Support for <code><a
href="http://wiki.debian.org/SHPort">SuperH</a></code> is expected soon.
Notice that even though some architectures are dropped for a given the release
there still might be a way to install and upgrade using the latest
<samp>sid</samp>.
</p>
<hr>
<h2><a name="s-morekernels"></a>15.5 More kernels</h2>
<p>
In addition to Debian GNU/Hurd, Debian is being ported also to BSD kernels,
namely to <code><a
href="http://www.debian.org/ports/kfreebsd-gnu/">FreeBSD</a></code>. This port
runs on both AMD64 (&quot;kfreebsd-amd64&quot;) and traditional Intel
(&quot;kfreebsd-i386&quot;).

The Debian GNU/Linux FAQ
<br>Chapter 14 - Redistributing Debian GNU/Linux in a commercial product
</h1>
<hr>
<h2><a name="s-sellcds"></a>14.1 Can I make and sell Debian CDs?</h2>
<p>
Go ahead. You do not need permission to distribute anything we have
<em>released</em>, so that you can master your CD as soon as the beta-test
ends. You do not have to pay us anything. Of course, all CD manufacturers
must honor the licenses of the programs in Debian. For example, many of the
programs are licensed under the GPL, which requires you to distribute their
source code.
</p>
<p>
Also, we will publish a list of CD manufacturers who donate money, software,
and time to the Debian project, and we will encourage users to buy from
manufacturers who donate, so it is good advertising to make donations.
</p>
<hr>
<h2><a name="s-packagednonfree"></a>14.2 Can Debian be packaged with non-free software?</h2>
<p>
Yes. While all the main components of Debian are free software, we provide a
non-free directory for programs that are not freely redistributable.
</p>
<p>
CD manufacturers <em>may</em> be able to distribute the programs we have placed
in that directory, depending on the license terms or their private arrangements
with the authors of those software packages. CD manufacturers can also
distribute the non-free software they get from other sources on the same CD.
This is nothing new: free and commercial software are distributed on the same
CD by many manufacturers now. Of course we still encourage software authors to
release the programs they write as free software.
</p>
<hr>
<h2><a name="s-childistro"></a>14.3 I am making a special Linux distribution for a &quot;vertical market&quot;. Can I use Debian GNU/Linux for the guts of a Linux system and add my own applications on top of it?</h2>
<p>
Yes. Debian-derived distributions are being created both in close cooperation
with the Debian project itself and by external parties. One can use the
<code><a href="http://cdd.alioth.debian.org/">Custom Debian
Distributions</a></code> framework to work together with Debian; <code><a
href="http://www.skolelinux.org/">Skolelinux</a></code> is one such project.
</p>
<p>
There are several other Debian-derived distributions already on the market,
such as Progeny Debian, Linspire, Knoppix and Ubuntu, that are targeted at a
different kind of audience than the original Debian GNU/Linux is, but use most
of our components in their product.
</p>
<p>
Debian also provides a mechanism to allow developers and system administrators
to install local versions of selected files in such a way that they will not be
overwritten when other packages are upgraded. This is discussed further in the
question on <a href="ch-customizing.en.html#s-divert">How do I override a file
installed by a package, so that a different version can be used instead?,
Section 11.8</a>.
</p>
<hr>
<h2><a name="s-commercialdebs"></a>14.4 Can I put my commercial program in a Debian &quot;package&quot; so that it installs effortlessly on any Debian system?</h2>
<p>
Go right ahead. The package tool is free software; the packages may or may not
be free software, it can install them all.

The Debian GNU/Linux FAQ
<br>Chapter 5 - Software available in the Debian system
</h1>
<hr>
<h2><a name="s-apps"></a>5.1 What types of applications and development software are available for Debian GNU/Linux?</h2>
<p>
Like most Linux distributions, Debian GNU/Linux provides:
</p>
<ul>
<li>
<p>
the major GNU applications for software development, file manipulation, and
text processing, including gcc, g++, make, texinfo, Emacs, the Bash shell and
numerous upgraded Unix utilities,
</p>
</li>
</ul>
<ul>
<li>
<p>
Perl, Python, Tcl/Tk and various related programs, modules and libraries for
each of them,
</p>
</li>
</ul>
<ul>
<li>
<p>
TeX (LaTeX) and Lyx, dvips, Ghostscript,
</p>
</li>
</ul>
<ul>
<li>
<p>
the Xorg windowing system, which provides a networked graphical user interface
for Linux, and countless X applications including the GNOME, KDE and Xfce
desktop environments.
</p>
</li>
</ul>
<ul>
<li>
<p>
a full suite of networking applications, including servers for Internet
protocols such as HTTP (WWW), FTP, NNTP (news), SMTP and POP (mail) and DNS
(name servers); relational databases like PostgreSQL, MySQL; also provided are
web browsers including the various Mozilla products [<a
href="footnotes.en.html#f1" name="fr1">1</a>],
</p>
</li>
</ul>
<ul>
<li>
<p>
a complete set of office applications, including the OpenOffice.org
productivity suite, Gnumeric and other spreadsheets, WYSIWYG editors,
calendars.
</p>
</li>
</ul>
<p>
More than 18040 packages, ranging from news servers and readers to sound
support, FAX programs, database and spreadsheet programs, image processing
programs, communications, net, and mail utilities, Web servers, and even
ham-radio programs are included in the distribution. Another 560 software
suites are available as Debian packages, but are not formally part of Debian
due to license restrictions.
</p>
<hr>
<h2><a name="s-softwareauthors"></a>5.2 Who wrote all that software?</h2>
<p>
For each package the <em>authors</em> of the program(s) are credited in the
file <samp>/usr/share/doc/PACKAGE/copyright</samp>, where PACKAGE is to be
substituted with the package's name.
</p>
<p>
<em>Maintainers</em> who package this software for the Debian GNU/Linux system
are listed in the Debian control file (see <a
href="ch-pkg_basics.en.html#s-controlfile">What is a Debian control file?,
Section 7.4</a>) that comes with each package. The Debian changelog, in
<samp>/usr/share/doc/PACKAGE/changelog.Debian.gz</samp>, mentions the people
who've worked on the Debian packaging too.
</p>
<hr>
<h2><a name="s-pkglist"></a>5.3 How can I get a current list of programs that have been packaged for Debian?</h2>
<p>
A complete list is available from any of the <code><a
href="http://www.debian.org/distrib/ftplist">Debian mirrors</a></code>, in the
file <samp>indices/Maintainers</samp>. That file includes the package names
and the names and e-mails of their respective maintainers.
</p>
<p>
The <code><a href="http://packages.debian.org/">WWW interface to the Debian
packages</a></code> conveniently summarizes the packages in each of about
thirty &quot;sections&quot; of the Debian archive.
</p>
<hr>
<h2><a name="s-buildenv"></a>5.4 How can I install a developer's environment to build packages?</h2>
<p>
If you want to build packages in your Debian system you will need to have a
basic development environment, including a C/C++ compiler and some other
essential packages. In order to install this environment you just need to
install the <code>build-essential</code>. This package is a meta-package or
place-holder package which depends on the standard development tools one needs
to build a Debian package.
</p>
<p>
Some software can, however, need additional software to be rebuilt, including
library headers or additional tools such as <code>autoconf</code> or
<code>gettext</code>. Debian provides many of the tools needed to build other
software as Debian packages.
</p>
<p>
Finding which software is precisely required can be tricky, however, unless you
are planning on rebuilding Debian packages. This last task is rather easy to
do, as official packages have to include a list of the additional software
(besides the packages in <code>build-essential</code>) needed to build the
pacakge, this is known as <samp>Build-Dependencies</samp>. To install all the
packages needed to build a given source package and then build said source
package you can just run:
</p>
<pre>
# apt-get build-dep <var>foo</var>
# apt-get source --build <var>foo</var>
</pre>
<p>
Notice that if you want to build the Linux kernels distributed by Debian you
will want to install also the <code>kernel-package</code> package. For more
information see <a href="ch-kernel.en.html#s-customkernel">What tools does
Debian provide to build custom kernels?, Section 10.2</a>.
</p>
<hr>
<h2><a name="s-missing"></a>5.5 What is missing from Debian GNU/Linux?</h2>
<p>
A list of packages which are still needed to be packaged for Debian exists, the
<code><a href="http://www.debian.org/devel/wnpp/">Work-Needing and Prospective
Packages list</a></code>.
</p>
<p>
For more details about adding the missing things, see <a
href="ch-contributing.en.html#s-contrib">How can I become a Debian software
developer?, Section 13.1</a>.
</p>
<hr>
<h2><a name="s-no-devs"></a>5.6 Why do I get &quot;ld: cannot find -lfoo&quot; messages when compiling programs? Why aren't there any libfoo.so files in Debian library packages?</h2>
<p>
Debian Policy requires that such symbolic links (to libfoo.so.x.y.z or similar)
are placed in separate, development packages. Those packages are usually named
libfoo-dev or libfooX-dev (presuming the library package is named libfooX, and
X is a whole number).
</p>
<hr>
<h2><a name="s-java"></a>5.7 (How) Does Debian support Java?</h2>
<p>
Several <em>free</em> implementations of Java technology are available as
Debian packages, providing both Java Development Kits as well as Runtime
Environments. You can write, debug and run Java programs using Debian.
</p>
<p>
Running a Java applet requires a web browser with the capability to recognize
and execute them. Several web browsers available in Debian, such as Mozilla or
Konqueror, support Java plug-ins that enable running Java applets within them.
</p>
<p>
Please refer to the <code><a
href="http://www.debian.org/doc/manuals/debian-java-faq/">Debian Java
FAQ</a></code> for more information.
</p>
<hr>
<h2><a name="s-isitdebian"></a>5.8 How can I check that I am using a Debian system, and what version is it?</h2>
<p>
In order to make sure that your system has been installed from the real Debian
base disks check for the existence of <samp>/etc/debian_version</samp> file,
which contains a single one-line entry giving the version number of the
release, as defined by the package <samp>base-files</samp>.
</p>
<p>
The existence of the program <samp>dpkg</samp> shows that you should be able to
install Debian packages on your system, but as the program has been ported to
many other operating systems and architectures, this is no longer a reliable
method of determining is a system Debian GNU/Linux.
</p>
<p>
Users should be aware, however, that the Debian system consists of many parts,
each of which can be updated (almost) independently. Each Debian
&quot;release&quot; contains well defined and unchanging contents. Updates are
separately available. For a one-line description of the installation status of
package <samp>foo</samp>, use the command <samp>dpkg --list foo</samp>. To
view versions of all installed packages, run:
</p>
<pre>
dpkg -l
</pre>
<p>
For a more verbose description, use:
</p>
<pre>
dpkg --status foo
</pre>
<hr>
<h2><a name="s-nonenglish"></a>5.9 How does Debian support non-English languages?</h2>
<ul>
<li>
<p>
Debian GNU/Linux is distributed with keymaps for nearly two dozen keyboards,
and with utilities (in the <samp>kbd</samp> package) to install, view, and
modify the tables.
</p>
<p>
The installation prompts the user to specify the keyboard he will use.
</p>
</li>
</ul>
<ul>
<li>
<p>
Vast majority of the software we packaged supports entering non-US-ASCII
characters used in other Latin languages (e.g. ISO-8859-1 or ISO-8859-2), and
a number of programs support multi-byte languages such as Japanese or Chinese.
</p>
</li>
</ul>
<ul>
<li>
<p>
Currently, support for German-, Spanish-, Finnish-, French-, Hungarian-,
Italian-, Japanese-, Korean-, Dutch-, Polish-, Portuguese-, Russian-, Turkish-,
and Chinese-language manual pages is provided through the
<samp>manpages-LANG</samp> packages (where LANG is the two-letter ISO country
code). To access an NLS manual page, the user must set the shell LC_MESSAGES
variable to the appropriate string.
</p>
<p>
For example, in the case of the Italian-language manual pages, LC_MESSAGES
needs to be set to 'italian'. The <code>man</code> program will then search
for Italian manual pages under <samp>/usr/share/man/it/</samp>.

<h2><a name="s-pine"></a>5.10 Where is pine?</h2>
<p>
Due to its restrictive license, it's in the non-free area. Moreover, since
license does not even allow modified binaries to be distributed, you have to
compile it yourself from the source and the Debian patches.
</p>
<p>
The source package name is <code>pine</code>. You can use the
<code>pine-tracker</code> package to be notified about when you need to
upgrade.
</p>
<p>
Note that there are many replacements for both pine and pico, such as
<code>mutt</code> and <code>nano</code>, that are located in the main section.
</p>
<hr>
<h2><a name="s-qmail"></a>5.11 Where is qmail/ezmlm/djbdns?</h2>
<p>
Dan J. Bernstein used to distribute <code><a
href="http://cr.yp.to/software.html">all software he has written</a></code>
with a restrictive license which does not allow modified binaries to be
distributed. In november 2007 however, Bernstein said &quot;[...] i have
decided to put all of my future and [...] past software into the public
domain&quot;. See <code><a href="http://cr.yp.to/distributors.html">FAQ from
distributors</a></code> for his distribution terms.
</p>
<p>
As of 2008-04, <code>daemontools</code>, <code>djbdns</code> and
<code>ucspi-tcp</code> are shipped with Debian lenny (in main). As of this
writing (2008-04), <code>qmail</code> is not yet packaged for Debian main; see
<code><a href="http://bugs.debian.org/457318">Bug #457318 (ITP
qmail)</a></code> for the current status.
</p>
<p>
As of 2008-04, <samp>publicfile</samp> and <samp>ezmlm</samp> were still not
free software. For <samp>ezmlm</samp>, there's the <code>ezmlm-src</code>
package in the non-free area.
</p>
<hr>
<h2><a name="s-flash"></a>5.12 Where is a player for Flash (SWF)?</h2>
<p>
Debian ships both <code>gnash</code> and <code>swfdec</code>: two free SWF
movie players.
</p>
<hr>
<h2><a name="s-googleearth"></a>5.13 Where is Google Earth?</h2>
<p>
Google Earth is available for GNU/Linux from Google's web site, but is not only
not Free Software, but is completely undistributable by a third party.
However, <code>googleearth-package</code> (in the contrib-section) might be
helpful in using this software.
</p>
<hr>
<h2><a name="s-voip"></a>5.14 Where is VoIP software?</h2>
<p>
Two main open protocols are used for Voice Over IP: SIP and H.323. Both are
implemented by a wide variety of software in Debian main. <code>ekiga</code>
is one of the popular clients.
</p>
<hr>
<h2><a name="s-nonfreewireless"></a>5.15 I have a wireless network card which doesn't work with Linux. What should I do?</h2>
<p>
Buy one which does :)
</p>
<p>
Alternatively, use <code>ndiswrapper</code> to use a driver for Windows (if you
have one) on your Linux system. See the <code><a
href="http://wiki.debian.org/NdisWrapper">Debian Wiki ndiswapper
page</a></code> for more information.

The Debian GNU/Linux FAQ
<br>Chapter 12 - Getting support for Debian GNU/Linux
</h1>
<hr>
<h2><a name="s-debiandocs"></a>12.1 What other documentation exists on and for a Debian system?</h2>
<ul>
<li>
<p>
Installation instructions for the current release: see <code><a
href="http://www.debian.org/releases/stable/installmanual">http://www.debian.org/releases/stable/installmanual</a></code>.
</p>
</li>
</ul>
<ul>
<li>
<p>
The Debian GNU/Linux reference covers many aspects of system administration
through shell-command examples. Basic tutorials, tips, and other information
are provided for many different topics ranging from system administration to
programming.
</p>
<p>
Get it from the <code>debian-reference</code> package, or at <code><a
href="http://www.debian.org/doc/user-manuals#quick-reference">http://www.debian.org/doc/user-manuals#quick-reference</a></code>.
</p>
</li>
</ul>
<ul>
<li>
<p>
The Debian Policy manual documents the policy requirements for the
distribution, i.e. the structure and contents of the Debian archive, several
design issues of the operating system etc. It also includes the technical
requirements that each package must satisfy to be included in the distribution,
and documents the basic technical aspects of Debian binary and source packages.
</p>
<p>
Get it from the <code>debian-policy</code> package, or at <code><a
href="http://www.debian.org/doc/devel-manuals#policy">http://www.debian.org/doc/devel-manuals#policy</a></code>.
</p>
</li>
</ul>
<ul>
<li>
<p>
Documentation developed by the Debian Documentation Project. It is available
at <code><a
href="http://www.debian.org/doc/">http://www.debian.org/doc/</a></code> and
includes user guides, administration guides and security guides for the Debian
GNU/Linux operating system.
</p>
</li>
</ul>
<ul>
<li>
<p>
Documentation on installed Debian packages: Most packages have files that are
unpacked into <samp>/usr/share/doc/PACKAGE</samp>.
</p>
</li>
</ul>
<ul>
<li>
<p>
Documentation on the Linux project: The Debian package <code>doc-linux</code>
installs all of the most recent versions of the HOWTOs and mini-HOWTOs from the
<code><a href="http://www.tldp.org/">Linux Documentation Project</a></code>.
</p>
</li>
</ul>
<ul>
<li>
<p>
Unix-style `man' pages: Most commands have manual pages written in the style of
the original Unix 'man' files. For instance, to see the manual page for the
command `ls', execute <samp>man ls</samp>. Execute <samp>man man</samp> for
more information on finding and viewing manual pages.
</p>
<p>
New Debian users should note that the 'man' pages of many general system
commands are not available until they install these packages:
</p>
<ul>
<li>
<p>
<samp>man-db</samp>, which contains the <samp>man</samp> program itself, and
other programs for manipulating the manual pages.
</p>
</li>
</ul>
<ul>
<li>
<p>
<samp>manpages</samp>, which contains the system manual pages. (see <a
href="ch-software.en.html#s-nonenglish">How does Debian support non-English
languages?, Section 5.9</a>).
</p>
</li>
</ul>
</li>
</ul>
<ul>
<li>
<p>
GNU-style `info' pages: User documentation for many commands, particularly GNU
tools, is available not in `man' pages, but in `info' files which can be read
by the GNU tool <samp>info</samp>, by running <samp>M-x info</samp> within GNU
Emacs, or with some other Info page viewer.
</p>
<p>
Its main advantage over the original `man' pages are that it is a hypertext
system. It does <em>not</em> require the WWW, however; <samp>info</samp> can
be run from a plain text console. It was designed by Richard Stallman and
preceded the WWW.
</p>
</li>
</ul>
<p>
Note that you may access a lot of documentation on your system by using a WWW
browser, through `dwww', `dhelp' or `doccentral' commands, found in respective
packages, or by using `yelp'.
</p>
<hr>
<h2><a name="s-onlineresources"></a>12.2 Are there any on-line resources for discussing Debian?</h2>
<p>
Yes. In fact, the main method of support Debian provides to our users is by
the way of e-mail. We'll give some details on that, and mention some other
useful resources. Even more resources are listed at the <code><a
href="http://www.debian.org/support">Debian Support webpage</a></code>.
</p>
<hr>
<h3><a name="s12.2.1"></a>12.2.1 Mailing lists</h3>
<p>
There are a lot of <code><a
href="http://www.debian.org/MailingLists/">Debian-related mailing
lists</a></code>.
</p>
<p>
On a system with the <code>doc-debian</code> package installed there is a
complete list of mailing lists in
<code>/usr/share/doc/debian/mailing-lists.txt</code>.
</p>
<p>
Debian mailing lists are named following the pattern
debian-<var>list-subject</var>. Examples are debian-announce, debian-user,
debian-news. To subscribe to any list debian-<var>list-subject</var>, send
mail to debian-<var>list-subject</var>-request@lists.debian.org with the word
&quot;subscribe&quot; in the Subject: header. Be sure to remember to add
<em>-request</em> to the e-mail address when using this method to subscribe or
unsubscribe. Otherwise your e-mail will go to the list itself, which could be
embarrassing or annoying, depending on your point of view.
</p>
<p>
You can subscribe to mailing lists using the <code><a
href="http://www.debian.org/MailingLists/subscribe">WWW form</a></code>. You
can also un-subscribe using a <code><a
href="http://www.debian.org/MailingLists/unsubscribe">WWW form</a></code>.
</p>
<p>
The list manager's e-mail address is <code><a
href="mailto:listmaster@lists.debian.org">listmaster@lists.debian.org</a></code>,
in case you have any trouble.
</p>
<p>
The mailing lists are public forums. All e-mails sent to the lists are also
copied to the public archive, for anybody (even non-subscribers) to browse or
search. Please make sure you never send any confidential or unlicensed
material to the lists. This includes things like e-mail addresses. Of
particular note is the fact that spammers have been known to abuse e-mail
addresses posted to our mailing lists. See the <code><a
href="http://www.debian.org/MailingLists/index.en.html#disclaimer">Mailing
Lists Privacy policy</a></code> for more information.
</p>
<p>
Archives of the Debian mailing lists are available via WWW at <code><a
href="http://lists.debian.org/">http://lists.debian.org/</a></code>.
</p>
<hr>
<h4><a name="s-mailinglistconduct"></a>12.2.1.1 What is the code of conduct for the mailing lists?</h4>
<p>
When using the Debian mailing lists, please follow these rules:
</p>
<ul>
<li>
<p>
Do not send spam. See the <code><a
href="http://www.debian.org/MailingLists/#ads">Debian mailing list advertising
policy</a></code>.
</p>
</li>
</ul>
<ul>
<li>
<p>
Do not flame; it is not polite. The people developing Debian are all
volunteers, donating their time, energy and money in an attempt to bring the
Debian project together.
</p>
</li>
</ul>
<ul>
<li>
<p>
Do not use foul language; besides, some people receive the lists via packet
radio, where swearing is illegal.
</p>
</li>
</ul>
<ul>
<li>
<p>
Make sure that you are using the proper list. <em>Never</em> post your
(un)subscription requests to the mailing list itself[<a
href="footnotes.en.html#f7" name="fr7">7</a>]
</p>
</li>
</ul>
<ul>
<li>
<p>
See section <a href="#s-bugreport">How do I report a bug in Debian?, Section
12.5</a> for notes on reporting bugs.
</p>
</li>
</ul>
<hr>
<h3><a name="s12.2.2"></a>12.2.2 Web forums</h3>
<p>
<code><a href="http://debianhelp.org/">debianHELP</a></code> and <code><a
href="http://forums.debian.net/">Debian User Forums</a></code> are web forums
on which you can submit questions about Debian and have them answered by other
users. (These are not officially part of the Debian project.)
</p>
<hr>
<h3><a name="s12.2.3"></a>12.2.3 Wiki</h3>
<p>
Solutions to common problems, howto's, guides, tips and other documentation can
be found at the constantly changing <code><a
href="http://wiki.debian.org/">Debian Wiki</a></code>.
</p>
<hr>
<h3><a name="s12.2.4"></a>12.2.4 Maintainers</h3>
<p>
Users can address questions to individual package maintainers using e-mail. To
reach a maintainer of a package called xyz, send e-mail to
<em>xyz@packages.debian.org</em>.
</p>
<hr>
<h3><a name="s12.2.5"></a>12.2.5 Usenet newsgroups</h3>
<p>
Users should post non-Debian-specific questions to one of the Linux USENET
groups, which are named comp.os.linux.* or linux.*. There are several lists of
Linux Usenet newsgroups and other related resources on the WWW, e.g. on the
<code><a href="http://www.linux.org/docs/usenet.html">Linux Online</a></code>
and <code><a
href="http://www.linuxjournal.com/helpdesk.php">LinuxJournal</a></code> sites.
</p>
<hr>
<h2><a name="s-searchtools"></a>12.3 Is there a quick way to search for information on Debian GNU/Linux?</h2>
<p>
There is a variety of search engines that serve documentation related to
Debian:
</p>
<ul>
<li>
<p>
<code><a href="http://search.debian.org/">Debian WWW search site</a></code>.
</p>
</li>
</ul>
<ul>
<li>
<p>
<code><a href="http://groups.google.com/">Google Groups</a></code>: a search
engine for newsgroups.
</p>
<p>
For example, to find out what experiences people have had with finding drivers
for Promise controllers under Debian, try searching on the phrase <samp>Promise
Linux driver</samp>. This will show you all the postings that contain these
strings, i.e. those where people discussed these topics. If you add
<samp>Debian</samp> to those search strings, you'll also get the postings
specifically related to Debian.
</p>
</li>
</ul>
<ul>
<li>
<p>
Any of the common web spidering engines, such as <code><a
href="http://www.altavista.com/">AltaVista</a></code> or <code><a
href="http://www.google.com/">Google</a></code>, as long as you use the right
search terms.
</p>
<p>
For example, searching on the string &quot;cgi-perl&quot; gives a more detailed
explanation of this package than the brief description field in its control
file.
</p>
</li>
</ul>
<hr>
<h2><a name="s-buglogs"></a>12.4 Are there logs of known bugs?</h2>
<p>
Reports on unsolved (and closed) issues are publicly available: Debian
promissed to do so by stating &quot;We will not hide problems&quot; in the
<code><a href="http://www.debian.org/social_contract">Debian Social
Contract</a></code>.
</p>
<p>
The Debian GNU/Linux distribution has a bug tracking system (BTS) which files
details of bugs reported by users and developers. Each bug is given a number,
and is kept on file. Once it has been dealt with, it is marked as such.
</p>
<p>
Copies of this information are available at <code><a
href="http://www.debian.org/Bugs/">http://www.debian.org/Bugs/</a></code>.
</p>
<p>
A mail server provides access to the bug tracking system database via e-mail.
In order to get the instructions, send an e-mail to request@bugs.debian.org
with &quot;help&quot; in the body.
</p>
<hr>
<h2><a name="s-bugreport"></a>12.5 How do I report a bug in Debian?</h2>
<p>
If you have found a bug in Debian, please read the instructions for reporting a
bug in Debian. These instructions can be obtained in one of several ways:
</p>
<ul>
<li>
<p>
From the WWW. A copy of the instructions is shown at <code><a
href="http://www.debian.org/Bugs/Reporting">http://www.debian.org/Bugs/Reporting</a></code>.
</p>
</li>
</ul>
<ul>
<li>
<p>
On any Debian system with the <code>doc-debian</code> package installed. The
instructions are in the file
<code>/usr/share/doc/debian/bug-reporting.txt</code>.
</p>
</li>
</ul>
<ul>
<li>
<p>
By anonymous FTP. Debian mirror sites contain the instructions in the file
<samp>doc/bug-reporting.txt</samp>.
</p>
</li>
</ul>
<p>
You can use the package <code>reportbug</code> that will guide you through the
reporting process and mail the message to the proper address, with some extra
details about your system added automatically. It will also show you a list of
bugs already reported to the package you are reporting against in case your bug
has been reported previously, so that you can add additional information to the
existing bug report.
</p>
<p>
Expect to get an automatic acknowledgement of your bug report. It will also be
automatically given a bug tracking number, entered into the bug log and
forwarded to the debian-bugs-dist mailing list.

<h1>
The Debian GNU/Linux FAQ
<br>Chapter 9 - Keeping your Debian system up-to-date
</h1>
<hr>
<p>
A Debian goal is to provide a consistent upgrade path and a secure upgrade
process. We always do our best to make upgrading to new releases a smooth
procedure. In case there's some important note to add to the upgrade process,
the packages will alert the user, and often provide a solution to a possible
problem.
</p>
<p>
You should also read the Release Notes document that describes the details of
specific upgrades. It is shipped on all Debian CDs and available on the WWW at
<code><a
href="http://www.debian.org/releases/stable/releasenotes">http://www.debian.org/releases/stable/releasenotes</a></code>.
</p>
<hr>
<h2><a name="s-howtocurrent"></a>9.1 How can I keep my Debian system current?</h2>
<p>
One could simply execute an anonymous ftp call to a Debian archive, then peruse
the directories until one finds the desired file, and then fetch it, and
finally install it using <samp>dpkg</samp>. Note that <samp>dpkg</samp> will
install upgrade files in place, even on a running system. Sometimes, a revised
package will require the installation of a newly revised version of another
package, in which case the installation will fail until/unless the other
package is installed.
</p>
<p>
Many people find this approach much too time-consuming, since Debian evolves so
quickly -- typically, a dozen or more new packages are uploaded every week.
This number is larger just before a new major release. To deal with this
avalanche, many people prefer to use a more automated method. Several
different packages are available for this purpose:
</p>
<hr>
<h3><a name="s-aptitude-upgrade"></a>9.1.1 aptitude</h3>
<p>
APT is an advanced interface to the Debian packaging system. It features
complete installation ordering, multiple source capability and several other
unique features, see the User's Guide in
<samp>/usr/share/doc/apt-doc/guide.html/index.html</samp> (you will have to
install the <samp>apt-doc</samp> package).
</p>
<p>
<code>aptitude</code> is the recommended package manager for Debian GNU/Linux
systems. It is a text-based interface to APT using the curses library, and can
be used to perform management tasks in a fast and easy way.
</p>
<p>
Before you can use <code>aptitude</code>, you'll have to edit the
<samp>/etc/apt/sources.list</samp> file to set it up. If you wish to upgrade
to the latest stable version of Debian, you'll probably want to use a source
like this one:
</p>
<pre>
http://ftp.us.debian.org/debian stable main contrib non-free
</pre>
<p>
You can replace ftp.us.debian.org with the name of a faster Debian mirror near
you. See the mirror list at <code><a
href="http://www.debian.org/mirror/list">http://www.debian.org/mirror/list</a></code>
for more information.
</p>
<p>
More details on this can be found in the <code>sources.list(8)</code> manual
page.
</p>
<p>
To update your system, run
</p>
<pre>
aptitude update
</pre>
<p>
followed by
</p>
<pre>
aptitude dist-upgrade
</pre>
<p>
Answer any questions that might come up, and your system will be upgraded. See
also <a href="ch-pkgtools.en.html#s-aptitude">aptitude, Section 8.1.3</a>.
</p>
<hr>
<h3><a name="s-apt"></a>9.1.2 apt-get, dselect and apt-cdrom</h3>
<p>
<code>apt-get</code> is an APT-based command-line tool for handling packages,
and the APT dselect method is an interface to APT through <code>dselect</code>.
Both of these provide a simple, safe way to install and upgrade packages.
</p>
<p>
To use <code>apt-get</code>, install the <code>apt</code> package, and edit the
<samp>/etc/apt/sources.list</samp> file to set it up, just as for <a
href="#s-aptitude-upgrade">aptitude, Section 9.1.1</a>.
</p>
<p>
Then run
</p>
<pre>
apt-get update
</pre>
<p>
followed by
</p>
<pre>
apt-get dist-upgrade
</pre>
<p>
Answer any questions that might come up, and your system will be upgraded. See
also the <code>apt-get(8)</code> manual page, as well as <a
href="ch-pkgtools.en.html#s-apt-get">APT, Section 8.1.2</a>.
</p>
<p>
To use APT with <code>dselect</code>, choose the APT access method in dselect's
method selection screen (option 0) and then specify the sources that should be
used. The configuration file is <code>/etc/apt/sources.list</code>. See also
<a href="ch-pkgtools.en.html#s-dselect">dselect, Section 8.1.6.1</a>.
</p>
<p>
If you want to use CDs to install packages, you can use <code>apt-cdrom</code>.
For details, please see the Release Notes, section &quot;Setting up for an
upgrade from a local mirror&quot;.
</p>
<p>
Please note that when you get and install the packages, you'll still have them
kept in your /var directory hierarchy. To keep your partition from
overflowing, remember to delete extra files using <samp>apt-get clean</samp>
and <samp>apt-get autoclean</samp>, or to move them someplace else (hint: use
<code>apt-move</code>).
</p>
<hr>
<h3><a name="s-update_aptitude"></a>9.1.3 aptitude</h3>
<p>
<code>aptitude</code> is a text-based interface to the Debian package system.
It allows the user to view the list of packages and to perform package
management tasks such as installing, upgrading, and removing packages (see <a
href="ch-pkgtools.en.html#s-aptitude">aptitude, Section 8.1.3</a>). Actions
may be performed from a visual interface or from the command-line.
</p>
<p>
In command line, the actions are similar to that of APT, so to upgrade your
system run
</p>
<pre>
aptitude update
</pre>
<p>
followed by
</p>
<pre>
aptitude dist-upgrade
</pre>
<p>
To upgrade from a preview release, <code>aptitude</code> is the tool
recommended. Read the Release Notes at <code><a
href="http://www.debian.org/releases/stable/releasenotes">http://www.debian.org/releases/stable/releasenotes</a></code>.
</p>
<p>
For details, see the manual page <code>aptitude(8)</code>, and the file
<code>/usr/share/aptitude/README</code>
</p>
<hr>
<h3><a name="s-mirror"></a>9.1.4 mirror</h3>
<p>
This Perl script, and its (optional) manager program called
<code>mirror-master</code>, can be used to fetch user-specified parts of a
directory tree from a specified host <em>via</em> anonymous FTP.
</p>
<p>
<code>mirror</code> is particularly useful for downloading large volumes of
software. After the first time files have been downloaded from a site, a file
called <samp>.mirrorinfo</samp> is stored on the local host. Changes to the
remote file system are tracked automatically by <code>mirror</code>, which
compares this file to a similar file on the remote system and downloads only
changed files.
</p>
<p>
The <code>mirror</code> program is generally useful for updating local copies
of remote directory trees. The files fetched need not be Debian files. (Since
<code>mirror</code> is a Perl script, it can also run on non-Unix systems.)
Though the <code>mirror</code> program provides mechanisms for excluding files
names of which match user-specified strings, this program is most useful when
the objective is to download whole directory trees, rather than selected
packages.
</p>
<hr>
<h3><a name="s-dpkg-mountable"></a>9.1.5 dpkg-mountable</h3>
<p>
dpkg-mountable adds an access method called `mountable' to dselect's list,
which allows you to install from any file system specified in /etc/fstab. For
example, the archive could be a normal hard disk partition or an NFS server,
which it will automatically mount and umount for you if necessary.
</p>
<p>
It also has some extra features not found in the standard dselect methods, such
as provision for a local file tree (either parallel to the main distribution or
totally separate), and only getting packages which are required, rather than
the time-consuming recursive directory scan, as well as logging of all dpkg
actions in the install method.
</p>
<hr>
<h2><a name="s-upgradesingle"></a>9.2 Must I go into single user mode in order to upgrade a package?</h2>
<p>
No. Packages can be upgraded in place, even in running systems. Debian has a
<samp>start-stop-daemon</samp> program that is invoked to stop, then restart
running process if necessary during a package upgrade.
</p>
<hr>
<h2><a name="s-savedebs"></a>9.3 Do I have to keep all those .deb archive files on my disk?</h2>
<p>
No. If you have downloaded the files to your disk then after you have
installed the packages, you can remove them from your system, e.g. by running
<samp>aptitude clean</samp>.
</p>
<hr>
<h2><a name="s-keepingalog"></a>9.4 How can I keep a log of the packages I added to the system? I'd like to know when which package upgrades and removals have occured!</h2>
<p>
Passing the <samp>--log</samp>-option to <code>dpkg</code> makes
<code>dpkg</code> log status change updates and actions. It logs both the
<code>dpkg</code>-invokation (e.g.
</p>
<pre>
2005-12-30 18:10:33 install hello 1.3.18 2.1.1-4
</pre>
<p>
) and the results (e.g.
</p>
<pre>
2005-12-30 18:10:35 status installed hello 2.1.1-4
</pre>
<p>
) If you'd like to log all your <code>dpkg</code> invokations (even those done
using frontends like <code>aptitude</code>), you could add
</p>
<pre>
log /var/log/dpkg.log
</pre>
<p>
to your <code>/etc/dpkg/dpkg.cfg</code>. Be sure the created logfile gets
rotated periodically. If you're using <code>logrotate</code>, this can be
achieved by creating a file <code>/etc/logrotate.d/dpkg</code> with contents
</p>
<pre>
/var/log/dpkg {
missingok
notifempty
}
</pre>
<p>
More details on <code>dpkg</code> logging can be found in the
<code>dpkg(1)</code> manual page.
</p>
<p>
<code>aptitude</code> logs the package installations, removals, and upgrades
that it intends to perform to <code>/var/log/aptitude</code>. Note that the
<em>results</em> of those actions are not recorded in this file!
</p>
<p>
Another way to record your actions is to run your package management session
within the <code>script(1)</code> program.
</p>
<hr>
<h2><a name="s-autoupdate"></a>9.5 Can I automatically update the system?</h2>
<p>
Yes. You can use <code>cron-apt</code>, this tool updates the system at
regular interval by using a cron job. By default it just updates the package
list and download new packages without installing.
</p>
<p>
Note: Automatic upgrade of packages is <strong>NOT</strong> recommended in
<em>testing</em> or <em>unstable</em> systems as this might bring unexpected
behaviour and remove packages without notice.
</p>
<hr>
<h2><a name="s-aptproxy"></a>9.6 I have several machines how can I download the updates only one time?</h2>
<p>
If you have more than one Debian machine on your network, it is useful to use
<code>apt-proxy</code> to keep all of your Debian systems up-to-date.
</p>
<p>
<code>apt-proxy</code> reduces the bandwidth requirements of Debian mirrors by
restricting the frequency of Packages, Releases and Sources file updates from
the back end and only doing a single fetch for any file, independently of the
actual request it from the proxy. <code>apt-proxy</code> automatically builds
a Debian HTTP mirror based on requests which pass through the proxy.
</p>
<p>
For more details, see the apt-proxy homepage at <code><a
href="http://apt-proxy.sourceforge.net/">http://apt-proxy.sourceforge.net/</a></code>
</p>
<p>
Of course, you can get the same benefit if you are already using a standard
caching proxy and all your systems are configured to use it.

<h2><a href="ch-software.en.html#fr1" name="f1">1</a></h2>
<p>
These have been, however, rebranded and are provided with different names due
to trademark issues

<h2><a href="ch-ftparchives.en.html#fr2" name="f2">2</a></h2>
<p>
When the present-day sid did not exist, the FTP site organization had one major
flaw: there was an assumption that when an architecture is created in the
current unstable, it will be released when that distribution becomes the new
stable. For many architectures that isn't the case, with the result that those
directories had to be moved at release time. This was impractical because the
move would chew up lots of bandwidth.
</p>
<p>
The archive administrators worked around this problem for several years by
placing binaries for unreleased architectures in a special directory called
&quot;sid&quot;. For those architectures not yet released, the first time they
were released there was a link from the current stable to sid, and from then on
they were created inside the unstable tree as normal. This layout was somewhat
confusing to users.
</p>
<p>
With the advent of package pools (see <a href="#s-pools">What's in the
<samp>pool</samp> directory?, Section 6.10</a>), binary packages began to be
stored in a canonical location in the pool, regardless of the distribution, so
releasing a distribution no longer causes large bandwidth consumption on the
mirrors (there is, however, a lot of gradual bandwidth consumption throughout
the development process).
</p>
<h2><a href="ch-ftparchives.en.html#fr3" name="f3">3</a></h2>
<p>
<samp>dists/stable/main</samp>, <samp>dists/stable/contrib</samp>,
<samp>dists/stable/non-free</samp>, and <samp>dists/unstable/main/</samp>, etc.
</p>
<h2><a href="ch-ftparchives.en.html#fr4" name="f4">4</a></h2>
<p>
Historically, packages were kept in the subdirectory of <samp>dists</samp>
corresponding to which distribution contained them. This turned out to cause
various problems, such as large bandwidth consumption on mirrors when major
changes were made. This was fixed with the introduction of the package pool.
</p>
<p>
The <samp>dists</samp> directories are still used for the index files used by
programs like <samp>apt</samp>.
</p>
<h2><a href="ch-pkgtools.en.html#fr5" name="f5">5</a></h2>
<p>
Notice that there are ports that make this tool available with other package
management systems, like Red Hat package manager, also known as
<code>rpm</code>
</p>
<h2><a href="ch-pkgtools.en.html#fr6" name="f6">6</a></h2>
<p>
Although this can also lead to systems with more packages installed than they
actually need to work.
