progress-linux, as discussed in MR #142 ([1]) is a little known distro,
which appears to be little more than a personal project of the original
author of live-build.
given that, the expense of maintaining all of these old hacks for it
cannot be justified. it is not known whether or not live-build is even
used with respect to it since the author abandoned live-build some
years ago.
also, at least one past change in live-build possibly broke progress-linux
compatibility anyway, which would have required progress-linux users of
live-build to use a custom progress-linux config, or a progress-linux
fork of live-build, and there is no knowing how much of the hacks in this
"upstream" codebase any user of progress-linux currently relies upon.
and again, progress-linux appears to just be a personal project of
Daniel's, with afaik very little userbase. (Daniel seems to be the only
developer working on the project which speaks to how small it is).

677415f6d7 (2007) in v1.0~a2-1 added a hack
relating to the loop-aes-utils package and losetup. this commit bundled
a bunch of changes, it was not specific to the hack, and so info about the
hack is limited to a brief comment included within the related change in
defaults:
```
# Workaround for loop-aes-utils divertion
# (loop-aes-utils' losetup lacks features).
```
though it is very similar to the removed fdisk hack in that it seems that
one package may replace a binary from another, moving the original to a
new location, and this hack gives the user the opportunity to select the
original instead of the one put in its place, for use in LB.
the comment mentions a package called loop-aes-utils as being the package
that performs such a diversion, and that the need for the hack was that
losetup itself lacked features, presumably encryption support, and it is
clear that it is the losetup binary that is the focus of the diversion.
looking into the history of loop-aes-utils a little, this package was
dropped from debian back in 2012 (#680748), favouring encrytion support of
dm-crypt/cryptsetup.
double checking file contents of packages, only the mount package carries
an /sbin/losetup file, so presumably this means that dm-setup/cryptsetup
do not perform such a diversion of losetup (i.e. their use is exclusively
done directly).
since the possible diversion is simply gone, that completely removes any
point in having the hack of giving users choice between losetup and the
diverted one. so let's remove this obsolete hack...
8321653cb3 (from 2007) introduced a hack to
work around bug #445304 in gnu-fdisk for users who may have replaced fdisk
with the classic gnu version. the hack allowed users to select an alternate
fdisk binary to use to work around the buggy binary.
bug #445304 is marked as found in v1.0-1 and fixed in v1.2-1, though may
have been fixe din v1.1. it was marked fixed in 2009.
checking the package archive, gnu-fdisk does not actually exist anymore
in debian, with one exception - it is available for arm64 on sid via
debports, and that version is 1.3 so thus includes the necessary fix
anyway.
it is thus pointless now that we still carry this hack.

Current versions of the project files are built upon versions published
and licensed by Daniel Baumann, but are modified copies of those files and
thus need to be marked as such per licensing requirements (afaik he did
not pass along ownership / licensing rights to anyone when he left the
project). We should also be careful to not be misrepresenting such
modified copies as being attributed to Daniel.
Adding a new copyright line referring to "The Debian Live team" should
suffice for this.
The authorship block in man pages has also similarly been updated.
Notes:
- tweaked a copy of daniel copyright lines stating 2014 instead of 2015.
both of these cases were in files that i had personally introduced in
some of my past merged commits that moved some code around. i don't know
why they stated 2014.
- binary_onie was introduced in 2018, so that has a 2018 date instead of
2016 unlike the rest.
- 'efi-image' is a 3rd-party (Canonical Ltd) work that we bundle, but it
has been modified by 674794a8f4 and
36a3ba7634 so I similarly added a
debian live copyright line.
- 'grub-cpmodules' is similar. it was only changed by the indentation fix
of 36a3ba7634 but modification is
modification, and this does help cover any possible future changes that
might be made.
`false` and `none` make no sense as choices for this option. Here we
replace `false` with `none`, and remove `true`.
Note that `true` was treated as an alias for netinst (see the changes to
source_disk and and binary_disk).
For backwards compatibility we still allow `true` and `false` by converting
them to `netinst` and `none` respectively, whilst printing a warning to
encourage users to move to `netinst`/`none`.

`lb build` is a top level command and the one most users will want. listing
the secondary component build stages alongside it just confuses things.
here we clarify things by moving the second-level build stages to a
separate list.

This makes it possible to build an image against a first distribution
(--distribution-chroot) and have the resulting image point to another
distribution (--distribution-binary). We can use this to build against a
snapshot and have the result use the original distribution that was
snapshotted.
Closes: #888507
This option was removed in commit 7e633e77f (Moving grub and grub2
templates into shared bootloader config directory.), but the
documentation stayed around.
Before Stretch there was an special amd64 kernel in the i386 arch repo.
So if you wanted to install an amd64 kernel alongside an i386 system
you did not need an additional arch repo.
Debian added multiarch support. That way you can install library packages
from multiple architectures on the same machine.
So there is no longer a need for having an amd64 kernel in i386 arch repo.
You can add an amd64 arch repo to an i386 arch system and fetch the amd64
kernel from the am64 arch repo.
live-build can be setup to use several linux kernel flavours in a single
image.
So in the days previous to this patch you could issue:
lb config --linux-flavours "486 amd64"
to use both 486 and amd64 kernel flavours.
Adding additional arch support to linux flavours poses two problems:
* Packages need to have its arch suffix (e.g. amd64:amd64).
If the suffix is not there apt-get insists on search amd64 kernel
package on i386 arch repo and, of course, fails to find it.
* The rest of the code which handles labels (bootloader config files)
or installed filenames (kernel images themselves) do not use the arch suffix.
This patch adds foreign architecture package support to
linux kernel flavours having taken those problems into account.
Practical example usage: i386 system and extra amd64 kernel.
First add amd64 foreign architecture in your i386 system
thanks to:
dpkg --add-architecture amd64
apt-get update
.
Finally enable amd64 kernel from amd64 arch alongside the
i386 system's 686 kernel thanks to:
lb config --architectures i386 --linux-flavours "686 amd64:amd64"
Open Network Install Environment is an open image format used by
networking vendor to ship a standardised image for networking white
box switches.
ONIE hardware takes this image at boot and a script to chain load
into the final environment via kexec. We can support Debian and
derivatives on such systems by packing an ISO which then gets
unpacked, kexec'ed and live-booted.
A base ONIE system can be tested in QEMU by building a VM following
these instrunctions:
https://github.com/opencomputeproject/onie/blob/master/machine/kvm_x86_64/INSTALL
Once built, boot onie-recovery-x86_64-kvm_x86_64-r0.iso in QEMU/libvirt
and on the console there will be the terminal prompt. Check the IP
assigned by libvirt and then scp the live image (ssh access is enabled
as root without password...). Then the .bin can be booted with:
ONIE-RECOVERY:/ # onie-nos-install /tmp/live.hybrid.iso-ONIE.bin
The implementation is inspired by ONIE's own scripts that can be found
at:
https://github.com/opencomputeproject/onie/blob/master/contrib/debian-iso/cook-bits.sh
A new option, --onie (false by default) can be set to true to enable
building this new format in addition to an ISO.
An additional option, --onie-kernel-cmdline can be used to specify
additional options that the ONIE system should use when kexec'ing the
final image.
Note that only iso or hybrid-iso formats are supported.

Support for UEFI Secure Boot is modelled after how it currently works
in Ubuntu and on how it is going to work on Debian.
A minimal bootloader, shim, is used as the first-stage and it then
loads grub. Both have to be signed.
shim-signed is already available in Debian so the filenames are
already established, and the grub2 repository and packaging is common
between the 2 distros so we can already be reasonably sure of what it
is going to be.
So if both are available, copy /usr/lib/shim/shim[x64|aa64].efi.signed
as boot[x64|aa64].efi so that UEFI loads it first, and copy
/usr/lib/grub/[x86_64|arm64]-efi-signed/grub[x64|aa64].efi.signed as
grub[x64|aa64].efi.
This grub2 EFI monolithic image is currently hard-coded in grub2's
repository to look for a config file in efi/debian, so make a copy
of the previously added minimal grub.cfg that loads the real one in
that directory in both the fat32 and ISO 9660 partitions.
The new option --uefi-secure-boot can be set to auto (default,
enable or disable.
In auto, the lack of the signed EFI binaries is intentionally left as a
soft failure - live-build will simply fallback to using the locally
generated non-signed grub2 monolithic EFI binary as the only
bootloader. Given the difficulties surrounding the Secure Boot
signing infrastructure this approach gives the most flexibility and
makes sure things will "just work" once the packages are available,
without the need to change anything in the configuration.
This will also greatly help downstream distributions and users who
want to do self-signing.
The enable or disable options work as expected.
Closes: #821084
This option lets you use an alternate bootstrap script when running
debootstrap. Thanks to Sjoerd Simons <sjoerd@debian.org> for the initial
patch.
Closes: #790033
This work is based on debian-cd team work and uses,
as much as possible, the same mkisofs options
than the Debian Installation CD disk does.
It assumes that /boot/grub/grub.cfg (and other design items)
is generated by: binary_loopback_cfg .
It relies on efi-image and grub-cpmodules being setup
as build scripts on live-build package.
In the future event of these two files being moved
to a binary package (they are originally from:
src: live-installer) the binary_grub-efi script would have
to be rewritten to take the new paths into account.
