* 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 a custom
config tree, rather than embedded and maintenance intensive
code in live-build itself.

The list of files passed to Truncate() might contain absolute symlinks
pointing to files outside the chroot, which previously destroyed files on
the build host.
debootstrap is the official tool to bootstrap debian,
cdebootstrap has had the one or other bug making it
broken for times during the release cycles.
The extra effort of supporting both debootstrap
and cdebootstrap is hardly worth it since the bootstrap
stage is cached anyway.
If a local repository path is given as a mirror URL lets bind it into the
chroot. The local repository will be unmounted while processing "remove" or
latest by the exit function.
Comments in package lists used to work in live-build 3.x (although
possibly only as a side-effect of some other logic) and being able to
comment package is a useful feature (to explain why some packages are
included and to make it easy to uncomment some lines to add more useful
packages).
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.)
* Add function to output unique list of foreign architectures from an
expanded package list.
* If foreign architectures are detected, add unique architectures
to dpkg and update apt.
* This requires users to explicitly list at least _one_ package of a
foreign architecture in their package list (e.g. foo:arch) for any other
foreign arch dependencies to be handled appropriately.
