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.
There are case in CPC built images where we don't want to create an SBOM.
Add an argument in create_manifest which defaults to creating an SBOM, but can also skip generating an SBOM
A change in 2024 [0] was made to debootstrap in which the keyring is now
switched from ubuntu-archive-keyring.gpg to
ubuntu-archive-removed-keys.gpg after a given release goes EOL. This
means that the Release signature cannot be verified after EOL since the
Release is signed with the ubuntu-archive-keyring.gpg. It is expected
that we can continue to build any release even after the suite is
closed.
This change adds a debootstrap configuration to override this behavior
and ensure all of our images are verified against the main archive key.

Use consistent formatting across all architectures: 4-space indent,
two spaces after "linux", one space after "initrd". Also fix an extra
blank line before "fi" in amd64's UEFI section caused by f-string
interpolation.

Separate config generation from file I/O by having generate_grub_config()
and its helpers return strings. The base class make_bootable() now handles
writing grub.cfg.

The debian-cd scripts did this game of placing boot-related files in a
separate directory that was then passed to xorriso to include on the
ISO. Stop doing that and just put the files directly into the ISO root
that is already passed to xorriso.
Package contents were being extracted into subdirectories of the boot
tree (grub_dir, shim_dir), which meant the boot tree contained both
the final boot files and the raw package extractions. Extract packages
into scratch directories instead, copying only the needed files into
the boot tree. This also removes the grub_dir/shim_dir instance
variables and the create_dirs overrides, and moves copy_grub_modules
to a standalone function in grub.py.
