Commit 51624c1b444d034ac06d9d0d6e2c02f73e856aa1 introduced a regression, changing kernel name from vmlinux to vmlinux (default) on riscv64. This fixes the regression and the bug in recent riscv64 iso images (preventing boot).
Fixes: 51624c1b444d ("Place ISO artifacts directly into the ISO tree")

This reverts commit 9d10c8086541a42ab48799d23765251096c3d7fe.
Actually, the new infra is not completely ready yet. There were concerns
about opening up the firewall/proxy on the builders to a service that is
way less strictly controlled than the current Archive toolbox. We'll
need to address these concerns first, then we can proceed with the move.
Seed installation diverts initramfs install hooks.
As we move base layers to dracut, casper is still needed
for the live layer.
This regenerates initrds after live layers install initramfs-tools, to
make casper work, in case the base layer was using dracut.
Resolute is currently on kernel 7.0 so preseeding fails with a apparmor
feature mismatch given that the live-build/apparmor/generic tree is
used. Adding a 7.0 tree solves this.
Non-layered MAKE_ISO=yes builds (e.g. kubuntu) had no equivalent of
the lb_binary_layered kernel placement added in the previous commit:
lb binary_linux-image put the kernel in binary/casper/ but nothing
copied it into the ISO tree (CASPER_DIR).

04-kernel-bits.binary only handled ubuntu-server; desktop builds
(ubuntu, ubuntu-budgie, lubuntu, etc.) had no equivalent and so the
kernel never reached the ISO casper directory for MAKE_ISO=yes builds.
Centralise the logic in lb_binary_layered, which already knows which
passes are live passes and is where the kernel is subsequently removed
from the chroot overlay. The flavor is determined by convention:
- passes ending in .live (desktop builds) use LB_LINUX_FLAVOURS
- other live passes (server installer passes such as
"...installer.generic-hwe") encode the flavor as the final
dot-separated component of the pass name
The netboot sub-passes (e.g. installer.generic.netboot) are never
added to LIVE_PASSES, so is_live_layer already guards against them;
the explicit exit-0 that 04-kernel-bits.binary needed is not required.
MAKE_ISO is always "yes" when lb_binary_layered runs — every code path
that sets PASSES_TO_LAYERS=true also sets MAKE_ISO=yes — so no
conditional is needed.

For MAKE_ISO=yes builds, squashfs, kernel, initrd, manifests, and sizes
are now placed directly into config/iso-dir/iso-root/casper/ during the
build rather than creating livecd.* intermediates that get linked as
for-iso.* files and then copied into casper/ by isobuild.
This stops publishing the intermediate livecd.* artifacts so that only
livecd.*.iso and livecd.*.netboot.tar.gz are published for ISO builds.

Hooks that only source config/functions (not config/common) would fail
with "LIVECD_ROOTFS_ROOT: parameter not set" when calling setup_mountpoint
or any function that transitively calls it. This affected ubuntu, ubuntu-cpc,
and buildd hooks.
Rather than adding `. config/common` to every hook, prepend the
LIVECD_ROOTFS_ROOT assignment to config/functions at config time so it is
available to all callers automatically.
- Adding parition ordering using imagecraft
- Removing redundant locales install
- Better logging for empty ARCH and SUBPROJECT
- Using mktemp for mountpoint
- Added manifest and filelist generation
- Currently, we only produce minimal images for amd64
- Tested the changes by booting an instance on OVH
- Hook was also tested to be run in a local CPC Jenkins pipeline
Read http-proxy from --http-proxy flag or build-livefs.conf and pass it
to the VM at launch time via cloud-init user-data (apt.http_proxy /
apt.https_proxy). Also set package_update: true so cloud-init runs
apt-get update on first boot, removing the need for an explicit call.

Creates (or reuses) a per-suite LXD VM, mounts the livecd-rootfs
checkout into it, waits for the VM to be ready, installs dependencies,
and runs build-livefs inside the VM — keeping the host clean.

Provides a single command to run a livecd-rootfs build, replacing the
manual setup of auto/ symlinks and env vars that lpbuildd's
build_livefs.py encapsulates. Works from a git checkout, an installed
deb, or via the /usr/bin/build-livefs symlink.

Builds a real Ubuntu ISO in ~2-3 minutes (vs 30-60 for production)
by keeping the package set minimal (casper + linux-generic only) and
using lz4 squashfs compression.
Design:
- Two-pass layered build (PASSES_TO_LAYERS=true):
- base: installs casper
- base.generic (LIVE_PASSES): installs linux-generic, triggers
update-initramfs with CASPER_GENERATE_UUID=1 to embed UUID
- No package pool (POOL_SEED_NAME=), no universe, amd64 only
- SQUASHFS_COMP=lz4 (~10x faster than xz); create_squashfs() now
respects ${SQUASHFS_COMP:-xz} so all other projects are unaffected
- Germinate is skipped (only add_package is used, no add_task/pool)
New files:
- live-build/ubuntu-test-iso/hooks/01-test-iso.chroot_early
- live-build/ubuntu-test-iso/hooks/02-test-iso-kernel.binary
Modified:
- live-build/functions: honour $SQUASHFS_COMP in create_squashfs()
- live-build/gen-iso-ids: add ubuntu-test-iso -> Ubuntu-Test-ISO
- live-build/auto/config: IMAGEFORMAT, fs, COMPONENTS, germinate
skip, SQUASHFS_COMP default + per-project override, project block,
write SQUASHFS_COMP to config/common, lxd exclusion, hook copying

For no very good reason this is what debian-cd does, and what the grub
config isobuilder generates still expects. It probably makes sense to
switch to 'vmlinuz' like every other arch apart from ppc64el does but
for now I want to maintain compatibility with the old ISOs.
