If a configuration does not use services that depend on the
stateVersion, it does not need to be set.
This provides an incentive for services not to rely on
stateVersion, and not to burden users with this.
Invoke `install` separately for each directory to get ownership right --
i.e. not always owned by root. When owned by root, user sessions break
as no user processes are allowed to create directores there. On normal
systems the directories already exist, but in clean environments / NixOS
test VMs, the bug shows.
Before:
$ namei -l /home/user1/.cache/borg
f: /home/user1/.cache/borg
drwxr-xr-x root root /
drwxr-xr-x root root home
drwx------ user1 users user1
drwxr-xr-x root root .cache
drwxr-xr-x user1 users borg
After:
$ namei -l /home/user1/.cache/borg
f: /home/user1/.cache/borg
drwxr-xr-x root root /
drwxr-xr-x root root home
drwx------ user1 users user1
drwxr-xr-x user1 users .cache
drwxr-xr-x user1 users borg

The `darwin.builder` derivation had a gratuitous dependency
on the current Nixpkgs revision due to
`config.system.nixos.revision`. Setting the revision explicitly
to null fixes this problem and prevents the derivation from being
rebuilt on every change to Nixpkgs.
This adds a new ``parallelShutdown`` option that allows users to control
how many guests can be shut down concurrently. Allowing multiple virtual
machines to be shut down at the same time reduces the amount of time it
takes to reboot the host.

When the option list is empty, the fstab generator does not
automatically add "defaults" and generates a non-working fstab (since it
just emits two spaces around where the options would have been which is
only technically one fstab separator).
The `freeformType` of `settings.publicinbox` in this module prevented
users from setting settings on the `publicinbox` section itself (which
is necessary for making e.g. IMAP work correctly), and only allowed
configuration of nested per-inbox sections.
In general I believe that these overly specific types which are
traditional in NixOS, and this kind of config generation, are a huge
footgun. This commit is the least invasive change that makes the
module work correctly.
This brings back the ability to e.g. configure sane-airscan with
`environment.etc."sane.d/airscan.conf".text = ...`.
(AFAICT, sane-airscan loads all config files it finds, so it'll first
load the one from the nixos hardware.sane.* configuration, then the user
specified one in /etc/sane.d/airscan.conf.)
