Without casper in the minimal.standard.live seed for flavors using the
new ubuntu-desktop-installer (or derivitives thereof), casper cannot
create a live user. Without this live user, Ubuntu Studio has been
experiencing the inability to login automatically from either the GUI or
manually from a TTY. This leaves the boot at a black screen with a mouse
cursor. This commit is an attempt to avoid the same situation. Previous
assessments of omitting casper from this line appear to have been
incorrect.
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
Now that kernel names use expected -generic flavour, and kernels are
installed in the live layer, we can go back to stock behaviour of
auto/build noticing that binary hooks are called on a live layer and
executing the extraction & rename of the kernel flavours.
BTW we can even later expand that to support 2 generic abis, and
calling the bigger one the hwe generic such that can also remove
./live-build/ubuntu-server/hooks/04-kernel-bits.binary.
This fixes ubuntu arm64+x13s that is unable to find
ubuntu-x13s.kernel-laptop as due to this hook, which currently
produces ubuntu.kernel-generic in error which is not at all expected
by ubuntu-cdimage. Also this unbreaks producing oem & intel-iot
images, although we will build these in 24.04 only next.
This reverts ubuntu daily-live to use `--linux-flavours
laptop-generic-hwe-22.04` instead of `--linux-flavours none
--linux-packages=none --initramfs=none`, like it did in lunar and
pre-canary-image or images that install kernel in live layer.

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.
Add mapping to use laptop-23.10 kernel. Ensure that
enhanced-secureboot is only setup on amd64 arch.

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.
