ssh-import-id is part of the server-minimal task, which means it and
openssh-server are always installed by Subiquity regardless of user
choice. Since we can't update the Task headers post release,
ensure that openssh-server, openssh-sftp-server, and ssh-import-id
are not included in the minimal and full layers by purging them
in a dedicated hook.
Altering a file maintained by a package can lead to unexpected behaviou expecially in
this case where packages are being removed and added.
Instead use `dpkg-divert` to allow us to mock `lxd` to `true` to allow `unminimize` to work
without error and to avoid installing of the `lxd` snap.
`--force` implies that we wish not to fail `rm` even if the file is not present.
This was not our intention and as such can be removed.
Also use short option `-v` for verbose output as per the test of the code base.
The unminimize script will try to install the lxd snap using the shim script
`/usr/sbin/lxd` from the lxd-installer package.
Previously `unminimize` was using `snap`
to install `lxd` directly which was being diverted by diverting the `snap` command.
This is no longer the case so we can remove `/usr/sbin/lxd` from the lxd-installer package
if it exists and then redirect any calls to `/usr/sbin/lxd` to `/bin/true`.
live-build/auto/config:
- for Ubuntu Server live images and the arm64+tegra full arch, build a
tegra variant with linux-nvidia-tegra as the flavor and
linux-nvidia-tegra as the kernel meta-package
- default to nvidia-$SUBARCH as the kernel flavor and enable all
components for all images using arm64+tegra as full arch
hooks/03-kernel-metapkg.chroot_early:
- use linux-nvidia-tegra as kernel meta-package for the nvidia-tegra
flavor
- drop ds-identify policy, not needed with improved cloud config
- drop disabling network, doesn't work with ip=
- fixup setting up the INSTALLER_ROOT mountpoint
- enable cloud-init
- make cloud-init handle the default/baked in networking configuration
- install and enable openssh-server for the installation only
- provide cloud.cfg that generates random installer user password
- disable subiquity on sclp_line0 line based console
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.
ubuntu-cdimage/debian-cd/tools/add_live_filesystem helpfully adds a
'filesystem.' prefix to the squashfs, hence the name of the file
didn't match what's on disk.
Remove wants from local-fs.target, add wants from the uuid device instead.
Tested by applying these changes from pre-pivot-root by modifying
/root files in place whilst booting with break=bottom.
- 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.
