This is a fixup for c1ae82f448.
nix' `passAsFile` does not create empty files for variables that are
`null`.
This results in the following error for units that have no overrides or
content, but are, e.g. `wantedBy`:
`mv: cannot stat '': No such file or directory`.
Minimal reproducer:
`systemd.units.empty.wantedBy = [ "multi-user.target" ];`
This is often necessary when a unit is loaded in via `systemd.packages`.
Related to #262907 (Django3 removal from nixpkgs).
This package already required an unreasonable amount of maintenance
regularly for a such small leaf-package. It has a few highly outdated
dependencies (e.g. flask 1, jinja2 2.11, sqlalchemy 1.3).
After at least each Python package-set update one had to fix up a lot of
dependencies to fix the package itself, so it was only useful on stable
branches. And having so much outdated software in a security-sensitive
piece of software seems questionable.
Finally, globin and I won't be available for maintaining this now that
Mayflower is migrating to another solution (and we'll do that as well)
and I'd expect this to bitrot extremely quick if we both bail out.
literalExpression triggers the following error when building the
manual:
Cacheable portion of option doc build failed.
Usually this means that an option attribute that ends up in documentation (eg `default` or `description`) depends on the restricted module arguments `config` or `pkgs`.
Remove the deprecated --models option, as models are now discovered
and loaded dynamically from all configured model dirs at runtime.
Allow setting up custom model directories, so wake words other than the
built-in ones can be used, e.g. from
https://github.com/fwartner/home-assistant-wakewords-collection.
I don't really understand why this is only for a single version, so I
figured I'd just add this to the test matrix to also cover this
test-case for each major. Now, there's also one thing less to take care of
when removing old postgresql versions.
As described in the release lifecycle docs from postgresql[1], v11 will
stop receiving fixes as of Nov 9 2023. This means it's EOL throughout
the entire lifetime of 23.11, so let's drop it now.
A lot of examples are also referencing postgresql_11. Where it's
sensible, use postgresql_15 as example now to avoid confusion.
This is also handy because the LLVM 16 fix for postgresql is not
available for postgresql 11 ;-)
