6d331d4d0b add 7.0 kernel apparmor features preseeds
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.

auto/build: install kernel into ISO tree for non-layered builds
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).

Move kernel ISO placement from hook into lb_binary_layered
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.

Source config/functions in hooks that call iso_install_kernel

Place ISO artifacts directly into the ISO tree
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.

fix: bake LIVECD_ROOTFS_ROOT into config/functions
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.

build-livefs-lxd: configure apt proxy and package_update via cloud-init
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.

build-livefs-lxd: helper to run build-livefs inside an LXD VM
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.

Add PROJECT=ubuntu-test-iso for fast end-to-end ISO testing
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

place kernel at /casper/vmlinux on riscv64
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.

7e3c74afac feat: Use same keyring for all releases
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.

Extract packages to scratch dirs instead of boot tree subdirs
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.

Move ubuntu-mini-iso to use isobuilder instead of debian-cd
Set MAKE_ISO=yes so ubuntu-mini-iso uses the standard isobuilder
flow in auto/build. The binary hook is simplified to just creating
kernel/initrd artifacts; isobuilder handles .disk metadata, boot
configuration, and ISO creation.

The mini-iso's custom grub.cfg (single iso-chooser-menu entry) is
generated by a project-specific path in AMD64BootConfigurator.

Replace the debian-cd git clone and shell script invocation in

Key changes to builder.py:

- make_iso() gets mkisofs_opts directly from the configurator
  instead of reading a serialized file
- add_live_filesystem() links kernel/initrd with names expected
  by the boot configurators (vmlinuz/initrd, hwe-vmlinuz/hwe-initrd)
- _extract_casper_uuids() updated for the new initrd naming scheme
- Refactor config storage to use a single _config dict
- Add limit_length parameter to Logger for long xorriso commands

Add Python boot configuration package
Add architecture-specific boot configurators that translate the
debian-cd boot shell scripts (boot-amd64, boot-arm64, boot-ppc64el,
boot-riscv64, boot-s390x) into Python.

The package uses a class hierarchy:
- BaseBootConfigurator: abstract base with common functionality
- GrubBootConfigurator: shared GRUB config generation
- UEFIBootConfigurator: UEFI-specific shim/ESP handling
- Architecture classes: AMD64, ARM64, PPC64EL, RISCV64, S390X

A factory function make_boot_configurator_for_arch() creates the
appropriate configurator for each architecture.

fix xorriso -map to include target path for riscv64
The -map option requires two arguments: the source filesystem path and
the target path in the ISO. Without the "/" target, xorriso fails.
This only affects riscv64, which uses native xorriso mode rather than
mkisofs compatibility mode.

Add isobuild tool to build installer ISOs
This adds a new tool, isobuild, which replaces the ISO-building
functionality previously provided by live-build and cdimage. It is
invoked from auto/build when MAKE_ISO=yes.

The tool supports:
 - Layered desktop images (Ubuntu Desktop, flavors)
 - Non-layered images (Kubuntu, Ubuntu Unity)
 - Images with package pools (most installers)
 - Images without pools (Ubuntu Core Installer)

The isobuild command has several subcommands:
 - init: Initialize the ISO build directory structure
 - setup-apt: Configure APT for package pool generation
 - generate-pool: Create the package pool from a seed
 - generate-sources: Generate cdrom.sources for the installed system
 - add-live-filesystem: Add squashfs and kernel/initrd to the ISO
 - make-bootable: Add GRUB and other boot infrastructure
 - make-iso: Generate the final ISO image

auto/config is updated to:
 - Set MAKE_ISO=yes for relevant image types
 - Set POOL_SEED_NAME for images that need a package pool
 - Invoke gen-iso-ids to compute ISO metadata

auto/build is updated to:
 - Remove old live-build ISO handling code
 - Invoke isobuild at appropriate points in the build

lb_binary_layered is updated to create squashfs files with
cdrom.sources included for use in the ISO.

Add gen-iso-ids tool to compute ISO metadata
Add a script to compute the values for .disk/info, the ISO volume ID,
and the "capproject" (capitalized project name) used in various places
in the ISO boot configuration.

This replaces the logic that was previously scattered across live-build
and cdimage.

ubuntu: delay display manager until snapd seeding completes
Add systemd drop-in to wait for snapd seeding completion before starting the
display manager. This improves the user experience as users now wait in
Plymouth for the installer to finish being seeded, instead of in GDM with only
the wallpaper visible. When GDM starts, the installer launches with minimal
delay.

01c80d8d0a ubuntu: fix snap components pulled from the wrong model
We have a mechanism in place to override a snap when building an image.
Unfortunately, we didn't factor this in when forcing optional components to be
included in the image.

This was okay before because the stable model and the dangerous model had the
same components declared.

But now that pc-kernel has different components in the stable and the dangerous
model, things are broken.

Indeed, when building the stable image, we tried to include the pc-kernel from
the stable model with the pc-kernel components from the dangerous model. But
they are not compatible.

Fixed by including components from the right model. If we're overriding a snap
with a definition from a different model, then pull the components from that
same model.

This used to be necessary when there was no kernel in 26.04/stable, but now

9164e58d83 ubuntu: build with grade: dangerous but keep most snaps from stable
Because some snaps are not yet in their respective stable channel in 26.04, the
build fails. When preparing the image we can add --snap options to override the
channel of the different snaps. But we can only do that if we're building with
grade: dangerous. As a workaround this issue, we build with the non-dangerous
ISO with the dangerous model, but keep the snaps on their original channel
defined in the non dangerous model.

ff6b3824d8 cpc/UEFI: name the GPT partition cloudimg-rootfs
To boot initrdless, the kernel supports a limited number of ways to
specify the location of the root filesystem[1]. One of them is to use
the PARTUUID (which will be different for every cloud-image), another is
to use the PARTLABEL (partition name). To allow the use of PARTLABEL in
the kernel command line and make our cloud-images more self-describing,
set the PARTLABEL to cloudimg-rootfs which is the same label we use for
the file system inside this partition.

To make our disk images more discoverable, we should use the correct
partition type for the root filesystem. This aligns with the
Discoverable Disk Image (DDI) specification developed by the UAPI
group[1] and makes our images more self-describing, e.g. with fdisk,

/dev/nbd0p1  2324480 7339998 5015519  2.4G Linux filesystem

and now after:

Device         Start     End Sectors  Size Type
/dev/nbd0p1  2324480 7339998 5015519  2.4G Linux root (x86-64)

left on device` errors when the binary hits `grub-install`. This commit
increases $imagesize to 2.5GB (in the binary as an override initially
implemented in ecaaf0484).

This commit also runs `df` just after the grub-pc && grub2-common

Understanding the parameters used by livecd-rootfs
==================================================
livecd-rootfs is a confusing codebase. One of the confusing things is
how information flows into and around the image build process. There
is IMAGEFORMAT and IMAGE_TARGETS and PROJECT and many other
variables. It is not obvious when looking at the code if a given
variable is something passed as a parameter or something derived from
it.
All (or almost all) production use of livecd-rootfs is via
launchpad-buildd so the set of potential parameters is limited by the
set of environment variables launchpad-build can set in response to
the build request.
The process from build request to environment live-build is run is a
little convoluted. The build request takes:
an archive -- where to get livecd-rootfs from
a distro_arch_series -- the series to get livecd-rootfs and build
a pocket -- pocket to get livecd-rootfs from, also influences if proposed is
used as a package source for the image being built
unique_key -- you cannot have more than one pending livefs build with the same
unique_key. does not affect the build at all.
version -- optional version string, see below. often a serial like 20250525.1
metadata_override -- combined with the metadata on the livefs itself to make
the metadata for this build.
(ref: https://launchpad.net/+apidoc/devel.html#livefs-requestBuild)
These parameters are stored on the livefsbuild object (ref:
https://git.launchpad.net/launchpad/tree/lib/lp/soyuz/model/livefsbuild.py#n372)
and converted into a set of args passed to launchpad-build by the
LiveFSBuildBehaviour class (ref:
https://git.launchpad.net/launchpad/tree/lib/lp/soyuz/model/livefsbuildbehaviour.py#n99).
Inside launchpad-build, these arguments are inspected by the
LiveFilesystemBuildManager.initiate method (ref:
https://git.launchpad.net/launchpad-buildd/tree/lpbuildd/livefs.py#n24)
which turns them into arguments for the BuildLiveFS lpbuild
"operation" which is what creates the environment live-build runs in
(ref:
https://git.launchpad.net/launchpad-buildd/tree/lpbuildd/target/build_livefs.py#n167).
These variables can be set for both lb config and lb build:
PROJECT (mandatory, comes from "project" in the metadata)
ARCH (set to the abi tag of the distroarchseries being built for)
ARCH_VARIANT (set to the isa tag of the distroarchseries being built for if it is
different from the abi tag)
SUBPROJECT (optional, comes from "subproject" in the metadata)
SUBARCH (optional, comes from "subarch" in the metadata)
CHANNEL (optional, comes from "subarch" in the metadata)
IMAGE_TARGETS (optional, comes from "image_targets" in the metadata
"image_targets" is a list. IMAGE_TARGETS is set to " ".join(image_targets))
REPO_SNAPSHOT_STAMP
(optional, comes from "repo_snapshot_stamp" in the metadata)
SNAPSHOT_SERVICE_TIMESTAMP
(optional, comes from "snapshot_snapshot_stamp" in the metadata)
COHORT_KEY
(optional, comes from "cohort-key" in the metadata)
launchpad-buildd also contains code to set http_proxy / HTTP_PROXY /
LB_APT_HTTP_PROXY but there does not appear to be any way to trigger
this when requesting a build.
In addition the following variables can be set for lb config only (why
are some things set for lb config only? no idea):
SUITE (set to the name of the distroarchseries being built for)
NOW (set to value of the 'version' argument to the build request,
defaults to strftime("%Y%m%d-%H%M%S"))
IMAGEFORMAT (optional, comes from "image_format" in the metadata)
PROPOSED (set to "1" if the pocket passed to the build request is proposed)
EXTRA_PPAS (optional, comes from "extra_ppas" in the metadata
"extra_ppas" is a list. EXTRA_PPAS is set to " ".join(extra_ppas))
EXTRA_SNAPS (optional, comes from "extra_snaps" in the metadata
"extra_snaps" is a list. EXTRA_SNAPS is set to " ".join(extra_snaps))
BUILD_TYPE (optional, the "type" (i.e. Daily or Release) of ISO being built,
goes into .disk/info on the ISO, defaults to Daily)
Here is an opinionated and slightly angry attempt to describe what
each of these is for:
PROJECT
-------
This is the big one, the main variable that defines what is being
built. It can be ubuntu, ubuntu-server, xubuntu, ubuntu-mini-iso, that
sort of thing. Generally PROJECT determines the set of packages
installed but it (unfortunately?) has a bit more impact than that.
It's unarguable that we need a parameter like this.
ARCH
----
The architecture being built for. This is always the same as `dpkg
--print-architecture` for us, we don't do any cross builds.
It's kind of redundant but it's not really a problem that this exists.
ARCH_VARIANT
------------
The "variant" being built for, i.e. the ISA tag of the
distroarchseries. Only set if this is different from the ABI tag.
This is definitely needed to be able to build images for variants.
SUBPROJECT
----------
This is used for some builds to build a different sort of build of the
project. It can be set to:
* "minimized" for ubuntu-cpc builds to make a minimal cloud image
* "minimal" for xubuntu builds to make a smaller ISO
* "desktop-preinstalled" for ubuntu builds to make a preinstalled
image instead of the parts for an installer.
* "buildd" for images to be used as build images by craft tools, and also
buildd chroots used on launchpad builders?
* "live" for ubuntu-server builds, historically to distinguish d-i
style installers from subiquity style installers
* "desktop" for ubuntu-core-installer builds, to influence which
model is use to build the ubuntu core system that will be
installed.
_This_ parameter is a total mess. The desktop-preinstalled use feels
particularly egregious.
SUBARCH
-------
This identifies the target machine more specifically than ARCH,
e.g. "tegra-jetson" or "licheerv". Used mostly but not exclusively for
preinstalled builds.
We probably do need something like this.
CHANNEL
-------
Influences which channel snaps included in the build are taken from
(via a few different mechanisms).
IMAGE_TARGETS
-------------
Passed for CPC (and ubuntu-oem, for some reason) builds to
`config/hooks.d/make-hooks` which uses it to select which binary hooks
to run (and so determines which artifacts get produced).
It is probably reasonable that this exists.
REPO_SNAPSHOT_STAMP
-------------------
Currently unused.
SNAPSHOT_SERVICE_TIMESTAMP
--------------------------
Also currently unused, and unclear how it differs from
REPO_SNAPSHOT_STAMP.
COHORT_KEY
----------
Used to make sure that different builds run at the same time don't get
different versions of snaps due to phasing differences.
This is a totally valid thing to need to supply.
http_proxy / HTTP_PROXY / LB_APT_HTTP_PROXY
-------------------------------------------
Nothing complex here!
SUITE
-----
This is the series being built (e.g. noble, questing). It is misnamed
really -- a suite is usually a combination of a series and a pocket
(noble-proposed, questing-security).
As with ARCH this is sort of redundant as we do builds in a chroot of
the series being built but OTOH it is definitely information the
build needs to know!
NOW
---
The serial for the build, e.g. 20250519 or 20240418.4.
It is a totally reasonable parameter.
IMAGEFORMAT
-----------
This is one of the more incoherently handled parameters. In rough
outline it is the filesystem of the image we produce.
Installer builds do not produce raw images, so this ends up being set
to 'plain' (which causes live-build to just leave the rootfs as a
directory tree) or 'none' (which causes live-build to do roughly the
same thing but in a different way?).
Image builds that use ubuntu-image set it to "ubuntu-image". These
builds do not call 'lb build' or 'lb binary'.
Other preinstalled images (mostly cpc images) set it to ext4 (but then
use live-build/ubuntu-cpc/hooks.d/remove-implicit-artifacts to remove
the output file that this causes live-build to produce...). Some
projects rely on this being set via metadata when building the project
it seems.
It can be set when starting an image build, but most builds do not and
the behavior when it is not set explicitly is pretty confusing.
This place is not a place of honor.
PROPOSED
--------
Should packages from proposed by included?
This is not really as useful as it used to be for a bunch of reasons
but it conceptually makes sense.
EXTRA_PPAS
----------
Extra archives to get packages from.
This is a space separated list by the time it gets to
livecd-rootfs. Each element of the list is of the form USER/NAME[:PIN]
where user is a Launchpad user/team name, NAME is the name of the ppa
to add and the optional colon-PIN at the end is the value to pin (in
the "man 5 apt_preferences: sense) packages from this PPA at.
Production builds shouldn't really use this but it's definitely useful
for development.
EXTRA_SNAPS
-----------
Extra snaps to include (but only for ubuntu-image based builds).
BUILD_TYPE
----------
Before release, the .disk/info on an ISO looks like:
Ubuntu-Server 26.04 LTS "Resolute Raccoon" - Daily amd64 (20260210)
after release it looks like:
Ubuntu-Server 26.04 LTS "Resolute Raccoon" - Release amd64 (20270210)
We could do a livecd-rootfs upload to change this (it only changes
once per cycle), but it's quicker and easier to manage this from the
code that triggers the livefs builds.

* Only publish the ISOs, not the other bits, now that we are publishing the
ISOs on cdimage.
* Fix mini iso to not contain a pool or squashfs.
[ Ryan Hill ]
* add 7.0 kernel apparmor features preseeds

We did remove it from multiple places, but this one was left and as a
consequence, the latest iso was still having snapd edge.

livecd-rootfs (26.04.24) resolute; urgency=medium
[ Allen Abraham ]
* Added a hook to produce a working minimal Ubuntu image using imagecraft
[ Michael Hudson-Doyle ]
* Various quality of life improvements for hacking on livecd-rootfs:
- Add a "ubuntu-test-iso" project that builds a not very useful ISO in 2-5 minutes.
- Add a build-livefs script that takes care of copying the auto scripts and
invoking lb clean/config/build with the right environment.
- Add a build-livefs-lxd script to run the above script in a lxd vm.

increases $imagesize to 2.5GB (in the binary as an override, initially
implemented in ecaaf0484 by dlalaj). Also now run `df` just after the
grub-pc && grub2-common installs to make for easier debugging in the future.
