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.

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).
Bug-Ubuntu: https://bugs.launchpad.net/bugs/1829333
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.
LP: #1826377
commit a993592 introduced an additional call to create_manifest
(and snap-seed-parse) to write binary/boot/filesystem.packages. This
caused duplicate snap lines in the qcow manifest. This is because the
live-build/auto/binary code assumes that after 'lb binary' is run the
filesystem.packages will only have debs and it calls snap-seed-parse to
add them to the file. The commit changed filesystem.packages in the
ubuntu-cpc uefi binary hook to include debs and snaps.
This patch keeps the intent of the prior patch, updating the
filesystem.packages file for the content of the uefi disk image, but
only writes a listing of debian packages to match the expected content
of filesystem.packages. The snaps will still be added in generic code
in live-build/auto/build.
When the "snap-tool" script encounters a core snap it will switch to
the "stable" channel if the channel was set to "stable/ubuntu-X.X". This
ensures that core snaps always come from one canonical source.
UbuntuStudio image builds have recently begun failing as a result of adding a
grub theme customization to their flavor, which they then try to apply by
running update-grub from their maintainer scripts. This fails with:
Setting up plymouth-theme-ubuntustudio (0.57) ...
update-alternatives: using /usr/share/plymouth/themes/ubuntustudio-logo/ubuntustudio-logo.plymouth to provide /usr/share/plymouth/themes/default.plymouth (default.plymouth) in auto mode
update-alternatives: using /usr/share/plymouth/themes/ubuntustudio-text/ubuntustudio-text.plymouth to provide /usr/share/plymouth/themes/text.plymouth (text.plymouth) in auto mode
update-initramfs: diverted by livecd-rootfs (will be called later)
/usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?).
dpkg: error processing package plymouth-theme-ubuntustudio (--configure):
installed plymouth-theme-ubuntustudio package post-installation script subprocess returned error exit status 1
Packages providing grub themes should be able to call update-grub from their
maintainer scripts, and they should be able to be installed under
livecd-rootfs. It's surprising to me that this hasn't been a problem before
now for any flavors.
We know that grub-probe should not be called as part of an image build, so
just use our standard helper function to divert it before running the chroot
stage and undivert it after.
When the magic-proxy script could not find a valid InRelease file for the
configured timestamp, it would fall back to serving the canonical version
of it. This meant that builds would succeed, even though snap-shotting the
repository failed.
This update makes the script return HTTP 404 when an InRelease by-hash
link for a given combination of mirror, suite and timestamp cannot be
found.
Installing policyrcd-script-zg2 doesn't quite do this because of the way
that live-build installs its own temporary version of policy-rc.d. The
only remotely sensible way I can see to deal with this is to create the
symlink manually.
When the REPO_SNAPSHOT_STAMP variable is set, the auto/build script will attempt
to launch a transparent HTTP proxy on port 8080, and insert an iptables rule to
redirect all outgoing HTTP requests to this proxy.
The proxy, contained in the `magic-proxy` Python script, examines each request
and silently overrides those pointing to InRelease files or files that are
listed in InRelease files. It will instead provide the contents of the requested
file as it was at REPO_SNAPSHOT_STAMP, by downloading the corresponding asset
"by hash".
Don't install gpg or gpg-agent when building buildd images for series
earlier than bionic. (In earlier series, those packages didn't exist
and gnupg was build-essential.)
- Do not run apt-get update (which can bring in package lists if we are
unlikely wrt publisher schedules).
- Run apt-get clean to clear out downloaded debs of curtin/casper and
dependencies.
- Do not install user-setup.
- Use the core snap from the base filesystem if present.
