[Impact]

systemd-repart is not (as of 246.6-1ubuntu1) packaged in the
Ubuntu/Debian packages of systemd - probably because it has an extra
dependency?

The bug reporter would like to use it in our new raspberry pi images
where they don't have cloud-init installed. The reporter is already
using systemd-growfs, but they are missing the nice partition resizing
part (so are using cloud-initramfs-growroot).

Furthermore, in the mkosi image builder
(https://github.com/systemd/mkosi), the systemd/mkosi developers would
like to start using systemd-repart for partitioning. Unfortunately,
they're currently blocked on this because 22.04 doesn't ship systemd-
repart. The upstream CI uses Github Actions which runs on Ubuntu Jammy
and will do so until the next Ubuntu LTS is released. If we have to wait
for the next LTS to be released, we'll have to wait for a considerable
amount of time before we're able to start using systemd-repart.

Being able to use systemd-repart will allow the systemd/mkosi developers to take advantage of its improved interface compared to sfdisk,
as well as its builtin protections against race conditions surrounding the use of loop devices. The systemd/mkosi developers expect to
be able to get rid of some nasty loop device failure in mkosi by using systemd-repart.

[Test Plan]
This is a missing extra executable. Once enabled it has self-tests in the build-time unit tests, and also a regression test in the autopkgtest 'upstream' suite.

[Where problems could occur]
Shipping systemd-repart will come with no additional risk. While there is a systemd-repart.service that runs on boot, it's configured to not do anything if no config files are shipped with the system or provided by the user. As such, the service, if enabled, will effectively be a noop. Aside from the service, there's the CLI tool systemd-repart and the accompanying man pages that will be shipped as part of the systemd package.

Given that there's no risk involved with enabling systemd-repart, and
given the useful features it provides, the systemd/mkosi developers
would like to request that systemd-repart be enabled in Ubuntu and
backported to Jammy so that they can start adopting it in mkosi.
