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!
In the past, we'd directly snap install lxd which defaults to
the latest/stable channel. However, whilst working on enhancing
unminimize, it was observed that we install this snap from
the stable/ubuntu-<version> channel instead.
This was also noted as a failure when running the CTF tests:
`lxd installed from latest/stable, not stable/ubuntu-23.10`
With the introduction of the 6.5 kernel for mantic on 13th September ago we are seeing image build failures
on the armhf builds. The build failure was `No kernel output for generic-lpae!`.
Introduced in the 6.4 kernel and therefore now also in 6.5 there is no generic-lpae flavor anymore. it's just generic now.
As such this commit updates the expected flavour for armhf to generic.
In a minimized image, the linux headers are stripped, so when
unminimizing it, we should restore those stripped headers
by installing the linux-virtual package.
The unminimize script previously just restored the system documentation
and translations, man pages, and installed ubuntu-minimal and ubuntu-standard
packages to provide the familiar Ubuntu minimal system. But such an image
never became an equivalent of base image.
Upon investigation and looking at how the base image is constructed -
https://git.launchpad.net/livecd-rootfs/tree/live-build/auto/config#n1108 -
we use the following things:
- minimal task
- standard task
- cloud-image task (which involves ubuntu-server)
- ubuntu-minimal package
- server task if arch != amd64
OTOH, in the unminimize script, we use the following:
(https://git.launchpad.net/livecd-rootfs/tree/live-build/auto/build#n286)
- ubuntu-minimal package
- ubuntu-standard package
So upon running some tests, it was found that if we install ubuntu-server
(with --fix-policy flag), we get the resulting image equivalent to that
of a base image.

The pi images contain redundant copies of cmdline.txt and config.txt in
the boot partition mount-point (which get hidden by the *actual* boot
partition). This commit removes those and simplifies the subarch check
(again, +raspi is the only subarch in use at this point on the Raspberry
Pi images)
systemd-resolved got moved out of the systemd package in kinetic and is
required for bootable buildd environement (as opposed to launchpad buildd)

Prior to dpkg/1.21.0, there was a bug where dpkg -V/--verify
couldn't list all the correct packages correctly but with
that being fix and in archive since Jammy, this works perfectly
but the syntax to report the missing files have changed. It
just prints 'missing' now. With that new format, we can now
fix the regex to simply list the packages.
With this patch, the unminimize script works flawlessly
on a minimized image.
This package is needed by ubuntu-advantage-tools for cloud images
only. u-a-t ultimately will drop this entirely in their next release.
(cf: https://github.com/canonical/ubuntu-pro-client/issues/2692)
So instead of putting this in the seeds and then having to deal
with the seed changes to Mantic (after its release) and SRU of
ubuntu-meta, I'd rather have changes in livecd-rootfs done. Once
python3-systemd dependency is dropped from u-a-t, we'll drop it
from livecd-rootfs in Mantic+, too.
For minimized images we do not want to install any recommended packages.
We can do this by setting APT::Install-Recommends to false in apt config
or by passing --no-install-recommends to apt-get install.
Armhf images install the `generic-lpae` kernel, while other ARCHes use the
standard `generic` kernel when building the "virtual" image flavour.
Code was looking for a kernel binary ending with -generic in armhf
builds, and failed. Add a special condition to handle armhf builds'
kernel ending with `generic-lpae`

With the switch to the ubuntu-cloud-minimal seed, we
don't really need to purge anything now. On the contrary,
the purging of packages if not installed, fails with the
exit code of 100.
Now that we have the cloud-minimal seed for minimized cloud
image builds, we should drop all the workarounds and hacks
we once needed when we were using the server seed. We can
directly use the new metapackage and get rid of the tasks and
other autoremoves, et al.
Package linux-allwinner has a kernel with the generic flavour as
dependency. Add this translation to our code checking the correct
installation.

According to the kernel team the Linux Meta package linux-allwinner shall
continue to be supplied. It will depend on generic packages.

Canonical Public Cloud's project seems a bad place to build images for
hardware devices however this is how things were done a we now need to
maintain this.
The recent change to mount the ESP on /boot breaks those images, instead
of adding more hacky things in the hook, create a dedicated target for
those images and use a different hook to build UEFI images.
live-build/auto/config:
- for Ubuntu Server live images and the arm64+tegra full arch, build a
tegra variant with linux-nvidia-tegra as the flavor and
linux-nvidia-tegra as the kernel meta-package
- default to nvidia-$SUBARCH as the kernel flavor for all images using
arm64+tegra as full arch
hooks/03-kernel-metapkg.chroot_early:
- use linux-nvidia-tegra as kernel meta-package for the nvidia-tegra
flavor
SUBARCH=visionfive2 is used to build images for the StarFive VisionFive 2
boards. For the device-tree we assume board revision 1.3B.

Evolve the seed to only ship the specific part useful to WSL users. This
allows to trim down the image size.
