If the previous if statement checking if PASSES_TO_LAYERS is true,
then the last return code be non-zero and a return statement with no
argument will return the error code of the if statement thus exiting
the script. This is not our intent. So we need to return 0 here when
layer name as already been registered
The unminimize script will try to install the lxd snap using the shim script
`/usr/sbin/lxd` from the lxd-installer package.
Previously `unminimize` was using `snap`
to install `lxd` directly which was being diverted by diverting the `snap` command.
This is no longer the case so we can remove `/usr/sbin/lxd` from the lxd-installer package
if it exists and then redirect any calls to `/usr/sbin/lxd` to `/bin/true`
This is a cherry pick forward port from Jammy livecd-rootfs version 2.765.37.

mount_disk_image function expects root partition to be at number 1. But
some images require the root partition to be at other some other number.
For example, EKS Anywhere images for bare metal are used with Tinkerbell
deployment with a default configuration that expects the root device to
be found at /dev/sda2. The knowledge of the root device path is needed
to modify certain files in the root filesystem (e.g. cloud-init configs)
for the machine to join Kubernetes cluster control plane.
The partition number can be changed in the hook by "sgidsk --transpose".
Allow the hook to use mount_disk_image with custom root partition number
by making it an optional third parameter that defaults to 1.
This makes the hook ok to use cross-flavor.
We could also move glib-compile-schemas to a separate hook, to ensure we never
silently fail because glib-compile-schemas is broken/missing.
When the files we're creating in the live layer have static content, ship
them in live-build/ubuntu/includes.chroot.minimal.standard.live instead of
generating them from live-build/ubuntu/hooks/020-ubuntu-live.chroot_early.
Also fixes the fact that
live-build/ubuntu/hooks/020-ubuntu-live.chroot_early was incorrectly writing
to /root in the previous upload instead of /usr.
Somewhere along the line, we started trying to add packages to the live
environment of flavor "preinstalled" images. But:
- we don't build preinstalled images for any flavors
- the preinstalled images for projects like cloud images and wsl are
explicitly excepted from this code
- the only desktop project we do produce preinstalled images for, Ubuntu
on Raspberry Pi, uses ubuntu-image for building so this code is never
reached
ppc64el still uses /boot/vmlinux so we need to determine the boot file name as non ppc64el use /boot/vmlinuz. This
is then used to determine the kernel major minor version installed so that the correct apparmor features can be used
during snap preseeding. This preseeding was failing for ppc64el for the mantic 6.5 kernel as the /boot/vmlinuz
being checked did not exist.
With the migration from linux-kvm to linux-virtual/generic for the mantic minimal
images we can now start building arm64 minimal cloud images.
When building initial test images we noticed that the flash-kernel package was being
installed. This is not required for EFI images.
This commit removes the flash-kernel package from the cloud images arm installs
The only images built using the livecd-rootfs ubuntu-cpc project for arm64 and armhf
which are not cloud images (which therefore do not require flash-kernel) are the
raspi images. raspi does require flash-kernel. But the raspi images use the
`ubuntu-server-raspi` task to install the flash-kernel. As such this non raspi
flash-kernel package install can be completely removed.
It also means that initramfs-tools and dracut-install are installed as these are dependencies
of flash-kernel package.
minimized cloud image policy, introduced in version 23.10.16, is to not install recommends for any package
installs during build. This is to keep the image as small as possible. This also extends to
the grub related packages.
This solves the problems detailed in LP: #2037075 and aligns other arches more with amd64 install of
grub/shim packages for both minimized and non minimized ubuntu-cpc cloud image builds.
When trying to make changes to refactor livecd-rootfs, it is difficult to
know what side effects a change may have because of the use of globs on
arch/subarch and the lack of an authoritative list of supported arch
combinations.
This assembles a list of all possible values for $ARCH:$SUBARCH by looking at
all existing uses of $SUBARCH in live-build/auto/config and combining with
etc/default-arches from ubuntu-cdimage:
$ grep + etc/default-arches |grep -vE '(trusty|xenial|bionic|focal)[[:space:]]|appliance'
It also includes a special-case *appliance* glob, because there are many
Ubuntu Core appliance builds and there may be more in the future, and we
don't want to have to update livecd-rootfs with a hard-coded list.
Otherwise, this includes all currently used / supported combinations. The
amd64+kassel subarch is referenced in the code, but stopped being built a
while ago because "end of contract"; and there are some older no-longer-used
subarchs for particular raspi variants, which there is work to clean up
separately. So this should be a no-op wrt buildability of any existing
images on mantic - and if not, that's important for us to know!
