Subiquity images mount /usr/lib/modules from a squashfs, which systemd
tries to unmount on shutdown, whilst they are still being in use. As
systemd-udevd kmod built-in's libkmod has modules.* files
memorymapped. This produces an warning on shutdown, flooding the
screen with messages as systemd switches to a more verbose
output. Specify LazyUnmount=yes on that mount, such that unmount call
succeeds without flooding the shutdown log.
When we encounter a failure in 'lb binary' the launchpad builders can
only surface the build output from stdout. If the binary hook failure
implicates the archive we can not determine fault without the apt
proxy log. This patch will dump the proxy log to stdout to aid in
debugging these failures.
As discussed and explained to Jibel and Didier on 17th of June, based
on canary image build logs, it showed clearly that lb controlled
initrd was only built once at the very first layer by
chroot_hacks. However, that is the wrong layer to build the final
initrd at, as at this point casper is not present yet and is not part
of the build.
Thus insure that chroot_hacks only runs at the live layer.
Ideally a subset of chroot_hacks should run on every layer, as each
layer should be squeaky clean, and most of layers without
initrds. However, jibel & didrocks are still implementing requested
patches to unbreak layer images and make each layer smaller. Hence
this minimal portion of the overall required work.

When getting the list of snaps to include on an image via germinate, we
process the snaps in alphabetical order. Currently we seed several
packages `gnome-foo` and also `gtk-common-themes`, the default provider
of `gtk-3-themes`. Since `gtk-common-themes` is alphabetically after
`gnome-foo`, the `seed.yaml` we generate is invalid when we are part way
through generating.
What we really care about, though, is not that the `seed.yaml` is always
valid at every step, but it is that it is valid at the *end* of seeding.
So for the germinate case, let's defer validation to happen once at the
end. Other callsites of `snap_preseed`, where callers are careful to
seed snaps in the right order, are unaffected by this.
Chroot deconfiguration should happen in the opposite order from chroot
configuration, so, for symmetry, undivert_grub should be called between
"lb chroot_debianchroot remove" and "lb chroot_sysfs remove".
The livecd.ubuntu-cpc.ext4 that is present in each build (plus kernel
and initrd) are not renamed from /build/binary/boot/filsystem.ext4
and friends until after the binary hooks are run, so this patch moves
from trying to perform this cleanup in a binary hook. Now the cleanup
will be run at the end of live-build/binary for the ubuntu-cpc project.
In parallel builds where a list of image targets are provided the build
may produce binaries that are not part of the named set of targets but
are created by series dependencies. These implicitly created binaries
may be generated by multiple builds but are unused as our convention for
the ubuntu-cpc project is to only consume binaries from the explicitly
named image targets; this avoid overwriting the same object by multiple
parallel builds.
This patch adds support for a 'provides' keyword for series files. It can
be specified multiple times per series file. The field is used by the
make-hooks script to generate a list of output files created explicitly by
the named image targets. The list is saved to the "explicit_provides"
file in the hooks output directory. In the case of the "all" target
this list would be empty. This list is consumed by the "final.binary"
hook file.
This patch adds support for optional final.binary hooks in hooks.d/base
and/or hooks.d/extra. These final.binary hooks are always included as
the last hook(s) if either exist with the hook in "extra" running last.
The base/final.binary hook includes logic to parse the "explicit_provides"
file generated by the make-hooks script and remove any binary output not
explicitly specified.
Some series files named unnecessary dependencies, specifically
disk-image, to keep output of implicit artifacts consistent between
parallel builds. These unnecessary dependencies are removed in this
patch.
This is apparently still required; without it snapd gives an error
message like:
stateengine.go:102: state ensure error: devicemgr: cannot proceed without seeding "core"
We are creating a derivative of disk-image, replacing the kernel with
linux-kvm, removing initramfs, and creating a qcow2 image.

Configure cloud-init to look for its seed in the vFAT boot partition on
raspberry pi images; the corresponding gadget is configured to place the
user-data, meta-data, and network-config files there.

This is another thing that goes unused when there is no human console user
(and we already don't have the locales themselves present on a minimal
image).

The addition of disk-image to series files in a prior commit required
some explanation. Without comment support in series files that was
not possible. This patch adds support for comments and adds those
comments as well.
The following targets have livecd.ubuntu-cpc.manifest (and
livecd.ubuntu-cpc.ext4) which differ in some way from the 'all'
target. They are all missing grub-efi and other modifications:
root-dir
squashfs
tarball
These targets do not depend on the 'disk-image' target. This means that
the ext4 produced will lack the uefi modifications (and any from the
disk-image target binary hooks).
Since the ext4 file is common to all builds there is a chance that a
parallel build from one of these targets could overwrite this artifact.
This patch ensures that all targets will produce consistent base output.
This avoids us having apt cache files in the final image.
For auto/build, we move the call to clean_debian_chroot to the end,
this also takes care of the caches generated by apt-get update
in case of a preinstalled-pool.
For layered, it's just a simple swap of the lines.
