It's not clear how to use this command in other systemd units, this
section gives a recommendation.
I realized that there's no explicit mention of `nextcloud-occ` in the
first place, so I wrote some introductory sentences as well.
Since 25.05 dbtype no longer defaults to sqlite and this yields an error
that is understandable enough but not easy to properly address.
Add an assert that is more explicit.
Before:
```
error: The option `nodes.nextcloud.services.nextcloud.config.dbtype' was accessed but has no value defined. Try setting the option.
```
After:
```
error:
Failed assertions:
- `services.nextcloud.config.dbtype` must be set explicitly (pgsql, mysql, or sqlite)
Before 25.05, it used to default to sqlite but that is not recommended by upstream.
Either set it to sqlite as it used to be, or convert to another type as described
in the official db conversion page:
https://docs.nextcloud.com/server/latest/admin_manual/configuration_database/db_conversion.html

See https://discourse.nixos.org/t/i-cannot-for-the-life-of-me-find-the-package-that-has-pg-config/66244/4
I decided against doing this in its own nixpkgs manual: the line
to draw is quite blurry already (e.g. we have documented our package
removal policy in here as well) and having to check two manuals for a
single subsystem feels pretty annoying to me.
The relevant part - where to find pg_config - is written at the top. I
decided to give a bit more context about the way our packaging works
since I realized a few times now that I don't remember all the details
about the problems we had in the past and having to look up individual
commit messages for that isn't very productive.
This, and commits to k3s and util-linux close#409339.
The util-linux.withPatches API was a temporary hack for the 25.05
release to fix Kubernetes, and is going away.
While we're at it, we should use util-linuxMinimal because we do not
need things such as systemd support for kubelet initialization.
If a Python package does not come with either `format` or `pyproject` we
consider it a setuptools build, that calls `setup.py` directly, which is
deprecated.
This change, as a first step, migrates a large chunk of these packages to
set setuptools as their explicit format
This is so we can unify the problem space for the next step of the
migration.
Remove the major version from the unit name and add an alias for the old
dovecot2 name.
Then restricts what the dovecot service can do, which is very interesting
given that the unit runs as root and spawns less-privileged processes
from there.
