this was previously not done in 8b109ffb96
to keep the renaming simple, but leaving the variable plural is a cause
for confusion.
since this property is stored in the INI style config/build config file
rather than a shell script based one, at the property there is already
singular, there was no need for a backwards compatibility hack.

whilst some parts of the codebase were set up to work with multiple types
specified, others did not work with it and would not necessarily be easy
to adjust. this thus makes some tweaks to adjust things accordingly.
- option renamed to singular form (maintaining backwards compatibility)
- a validation check has been added
- unnecessary glob style type references fixed
- checks with In_list changed to a direct singular comparison
- typo of type "netboot" written as just "net" fixed (though unreachable
so of no consequence; really the code could be removed but it's trivial)
Gbp-Dch: Short
as just done for grub2|loopback
the primary benefit here is that it means that user configs do not
have to carry copies of all files; they just carry the ones they
want to replace (or add).
Gbp-Dch: Short
`$_SOURCE` is always composed of `<foo>/${_BOOTLOADER}`, so we can just use
`${_BOOTLOADER}` as the basename, without calling `basename ${_SOURCE}`

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).

this function takes one or more required stage fileS _plural_, and exits
if any are missing (or at least it does now after the refactor).
let's rename it to make things more clear
Gbp-Dch: Short
as suggested by Raphaël
rather than have fixed stagefile filename strings at all in the scripts,
use `$(basename $0)` to use the name of the script (which is the same for
almost all cases anyway, and the stage files are supposed to be almost
exclusively unique per-script). we can thus simplify things by determining
the filename for most use cases within the functions themselves.
this does change the file used by a couple of scripts, affecting backwards
compatibility of executing live-build upon an existing partially or fully
completed build:
- binary_grub-pc used "binary_grub"
- chroot_includes used "includes.chroot"
care had to be taken for the following cases:
- there are some cases like bootstrap_cache, source_debian and
bootstrap_debootstrap which are dealing with more than one file, and/or
otherwise a filename that is not specific to the script itself exactly,
or should not be based upon its name.
- some cases like chroot_cache, bootstrap_cache and
chroot_install-packages need to append something to the end of the name
depending upon which pass/action mode the script is being executed with.
- furthermore in the bootstrap_cache case one of the filenames is used
within the bootstrap_debootstrap and thus needs very careful handling
to be certain that a change in filename of bootstrap_cache does not
break bootstrap_debootstrap.
Gbp-Dch: Short
- avoid all need to pass ".build/" path in stage file names into the
functions
- add a helper to remove a stage file (required to complete the above
properly)
- avoid duplicating filenames within scripts which makes them prone to
mistakes (some instances of which I've actually encountered and had
to fix)
Gbp-Dch: Short
Fixes the following
- Correct version (memtest86/memtest86+) shown instead of fixed 'memtest86+' text
- Ensure correct directory path always used by using replaceable placeholder
Gbp-Dch: Short
Combine the check+create done in each script. (The original functions
are still callable as before, but a new combined `Aquire_lockfile`
function can be called instead, as now used).
Note, a further simplification could be done in removing the passing of
the lock filename in as a parameter since every use of the functions is
with ".lock". The lock functions already have a fallback to ".build/lock"
though. Checking the history, the fallback used to be for a system wide
lock, which was then replaced with this config-tree specific one. As long
as that is not used implicitly by 3rd-party hooks then surely we are free
to change the fallback to ".lock" and further remove passing in a name as
a param...?

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.
These functions are specific to handling packages stored in the
cache, not other files. They are also always used with the same
`cache/packages.` prefix to the path.

LB_DEBIAN_INSTALLER_GUI defines whether or not to provide the graphical
installer. the installer_debian-installer script pays attention to it and
does not download it if not wanted. the actual bootloaders however
(both grub2/loopback and syslinux) ignore it, which leaves broken and
unwanted menu entries. this fixes that.

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
Since commit fdc9250bc (Changing package dependency checks within chroot
to work outside as well), Check_package automatically checks for
LB_BUILD_WITH_CHROOT and works inside as well as outside of the chroot,
so no need to check LB_BUILD_WITH_CHROOT before calling them.
Install_package and Remove_package are just a no-op when building
without chroot, so they can also be called unconditionally.
Restore_cache and Save_cache do not check LB_BUILD_WITH_CHROOT but it
it should not hurt to call them when not needed (which already happened
in some cases).
This commit makes all Check_package calls unconditional on
LB_BUILD_WITH_CHROOT.
For binary_syslinux, this fixes the check (which used outdated paths
outside the chroot since 7b6dfd9d1), for binary_grub-efi,
binary_package-lists and chroot_package-lists this simplifies the code
(but also causes the check to become package-based instead of file-based
on apt-based systems), and for binary_loadlin and binary_win32-loader
this adds the check outside the chroot which was previously missing.
* Added: functions/bootloaders.sh . This file adds bootloader functions that are heavily used in efi scenarios where a bootloader can act as a first or an extra bootloader.
Since the introduction of the new switch:
--bootloaders
you can setup it like this:
--bootloaders=syslinux,grub-efi
.
This means that syslinux is the first bootloader and grub-efi is the extra bootloader.
* Added new bootloader functions: Check_Non_First_Bootloader and Check_Non_Extra_Bootloader.
These functions let each one of the bootloaders abort the build because
they cannot perform a role either as a first bootloader or as an extra bootloader.
* Added bootloader functions: Check_First_Bootloader_Role, Check_Extra_Bootloader_Role and Check_Any_Bootloader_Role
These functions let bootloaders to force their default role in a single line.
At the same time many binary bootloaders were rewritten to make use of the new bootloader role functions explained above.
These roles were enforced:
binary_grub-legacy : First bootloader
binary_grub-pc : Either first or extra bootloader
binary_syslinux : Either first or extra bootloader
If a bootloader is tried to be used in a role that it's not meant to be used then the build fails because that might lead to a non-bootable system.
Note: OLDIFS use makes IFS to be reset to "" instead to it being unset.
Either we need to detect if old IFS was unset to unset it
or we need a proper way of setting it as a local variable.
Even more IFS it's not currently used in
Check_package (which it's called from: binary_hdd).
we should have a clean way of resetting/unsetting IFS when calling Check_package.
The other approach it's to explicitly define IFS with its default value in the
places inside live-build code where we implicitly suppose that it's going to have
its default value.
Future live-build versions will still allow to use casper,
but its configuration will be done differently by hooks
in the config tree, rather than embedded and maintenance intensive
code in live-build itself.
extlinux configuration for the bootable image is installed to
/boot/extlinux, matching the extlinux-install script in Debian.
From the configuration point of view it's still called "syslinux",
the same as the rest of the syslinux family (pxelinux, isolinux etc.)
