Jammy HWE is rolling to 5.19. the 5.19 kernel introduced more apparmor
features, specifically ipc. due to the roll, we now must support builds
with 2 different feature sets.
This specifically affects snap-preseeding, where if a snap_preseed is
run with a mismatched apparmor feature set, snap will require a restart
to match the running kernel's feature set. in the clouds, this can add
somehwere between 5-10s (as of checks on 20230404). This is a large boot
time performance hit.
Implementation is done at the `snap_validate_seed` function level. This
function is called in snap scenarios. It checks for an installed kernel
in the chroot, gets the major.min version, and checks for
apparmor/$KERN. If found, it will do a copy of the directory, providing
a naive override mechanism.
For CPC builds, we are adding a call to `snap_validate_seed` at the end
of affected hooks as well. This is a safe procedure to call, as it
reruns the snap_preseed for all snaps. By running at the end of build
processes, it ensures that any kernel changes done during the build are
taken into account.
Add a file build.info on etc/cloud
with the serial information

RISC-V boards tend to boot slowly.
We should provide progress information when booting.
Use 'efi=debug earlycon' on the Linux command line via new file

The Nezha and the LicheeRV boards do not have enough memory for an initrd
with most modules. Therefore the number of included modules has to be
reduced.
Create file /etc/initramfs-tools/conf.d/modules_list.conf
to set MODULES=list.

Remove redirections of type
command &1>2
Executing the command in the background and creating and empty file '2'
was never intended.
As the messages are information only redirecting to stderr would not make
sense either.

The LicheeRV Dock board comes with only 512MB of DRAM so the only difference
with a Nezha image is the fact that we have to remove
cryptsetup-initramfs package which makes the initrd too big for the
board to boot.
