for the live server build, i want to make a layer to install the kernel
into but do not want the layer itself to be published.
the implementation is a bit clunky but it works.
Some packages are in universe at release time then promoted to
the main pocket in -updates during the release lifecycle.
These packages should be considered by germinate when the root fs is
built (LP: #1921862)

Initialize passwords from sources.list.
Use urllib everywhere.
This way authentication is added to all the required requests.
And incoming headers, are passed to the outgoing requests.
And all the response headers, are passed to the original client.
And all the TCP & HTTP errors are passed back to the client.
Thus should avoiding hanging requests upon failure.
Also rewrite the URI when requesting things.
This allows to use private-ppa.buildd outside of launchpad.

With that, the Dockerfile modifications[0] currently done externally
are done now here. That means that the created rootfs tarball can be
directly used within a Dockerfile to create a container from scratch:
FROM scratch
ADD livecd.ubuntu-oci.rootfs.tar.gz /
CMD ["/bin/bash"]
[0]
https://github.com/tianon/docker-brew-ubuntu-core/blob/master/update.sh
This is a copy of the ubuntu-base project.
Currently ubuntu-base is used as a base for the docker/OCI container
images. The rootfs tarball that is created with ubuntu-base is
published under [0]. That tarball is used in the FROM statement of the
Dockerfile as base and then a couple of modifications are done inside
of the Dockerfile[1].
The ubuntu-oci project will include the changes that are currently
done in the Dockerfile. With that:
1) a Dockerfile using that tarball will be just a 2 line thing:
FROM scratch
ADD ubuntu-hirsute-core-cloudimg-amd64-root.tar.gz /
CMD ["/bin/bash"]
2) Ubuntu has the full control about the build process of the
docker/OCI container. No external sources (like [1]) need to be
modified anymore.
3) Ubuntu can publish containers without depending on the official
dockerhub containers[2]. Currently the containers for the AWS ECR
registry[3] use as a base[4] the official dockerhub containers. That's
no longer needed because a container just needs a Dockerfile described
in 1)
When the ubuntu-oci project has the modifications from [1] included,
we'll also update [1] to use the ubuntu-oci rootfs tarball as a base
and drop the modifications done at [1].
Note: Creating a new ubuntu-oci project instead of using ubuntu-base
will make sure that we don't break users who are currently using
ubuntu-base rootfs tarballs for doing their own thing.

shim-signed depends on grub-efi-amd64-signed, which in turn has
alternative depends on either `grub-efi-amd64 | grub-pc`. However to
support booting with either via shim&signed-grub and BIOS, the choice
must be made to install grub-pc, not grub-efi-amd64.
This makes images consistent with Ubuntu Deskop, Live Server, buildd
bootable images; all of which already do install grub-pc and
shim-signed.
LP: #1901906
When desktop-preinstalled image options were added in
38157b37487d244b27af33f7863e6b15253c8f94, for the raspi subarch, the
options listed there were not scoped for raspi subarch. This results
in those options getting also applied for the HYPERV
ubuntu:desktop-preinstalled image.
Thus scope the newly added options under raspi subarch case only.
Regression introduced in 38157b37487d244b27af33f7863e6b15253c8f94 when
desktop-preinstalled code branch was added, it dropped addint
ubuntu-desktop task. Instead it added ubuntu-desktop-raspi task, only
for the raspi subarch, which depends on ubuntu-desktop. But the hyperv
case, now ended up without ubuntu-desktop task.
It looks like introduction of "desktop-preinstalled" assumed, that it
is for raspi only, when in fact that code path now started to be used
for hyperv gallery image too.
The seed now specifies the lxd snap in focal as
'lxd=4.0/stable/ubuntu-20.04' which doesn't match the expectations of
the code with looks for lxd as the only snap in the seed for minimized
images. This patch updates the pattern to accept 'lxd' or 'lxd=*'.
Builds in LP with the Xenial kernel were happy with the recursive mount of
/sys inside the chroot while performing snap-preseeding but autopkgtests
with the groovy kernel failed. With the groovy kernel the build was
unable to unmount sys/kernel/slab/*/cgroup/* (Operation not permitted).
This patch mounts /sys and /sys/kernel/security in the chroot in the
same way we've added for binary hooks. This provides the paths under
/sys needed for snap-preseed while avoiding issues unmounting other
paths.
