Since https://github.com/NixOS/nixpkgs/pull/61321, local-fs.target is
part of sysinit.target again, meaning units without
DefaultDependencies=no will automatically depend on it, and the manual
set dependencies can be dropped.
The redis module currently fails to start up, most likely due to running
a chown as non-root in preStart.
While at it, I hardcoded it to use systemd's StateDirectory and
DynamicUser to manage directory permissions, removed the unused
appendOnlyFilename option, and the pidFile option.
We properly tell redis now it's daemonized, and it'll use notify support
to signal readiness.
In fontconfig’s 60-generic.conf, order of preference is estabilished for emoji
font family. Because fontconfig parses the config files in lexicographic order,
appending each <prefer> from <alias> element to the family’s prefer list
(to be prepended before the family) [1], our font family defaults stored
in 52-nixos-default-fonts.conf will take precedence. That is, of course, unless
the default „weak“ binding [2] is used. Emoji family binds strongly [3],
so we need to set binding to “same” for our <alias>es to be considered before
the ones from 60-generic.conf.
By default, we will set the option to all emoji fonts supported by fontconfig,
so that emoji works for user if they have at least one emoji font installed.
If they have multiple emoji fonts installed, we will use the fontconfig’s
order of preference [4].

With local-fs.target part of sysinit.target
(https://github.com/NixOS/nixpkgs/pull/61321), we don't need to add it
explicitly to certain units anymore, and can change dependencies like
they are in other distros (I picked from Google's official CentOS 7
image here).
Like them, use StandardOutput=journal+console to pipe google-*.service
output to the serial console as well.
It turns out that checking for the last mount time of an ext4 file
system isn't a very reliable way to check whether the file system was
properly unmounted.
When creating that test in the first place (88530e02b6),
I was reluctant to inspect the file system when the VM is down and was
searching for a way to check for a clean unmount *after* the file system
was mounted again to make sure we don't need to create a 512 MB raw
image on the host.
Fortunately however, when converting from qcow2, qemu-img actually
writes a sparse file, so for most file systems (that is, file systems
supporting sparse files) this shouldn't waste a lot of disk space.
So when investigating the flakiness, I found that whenever the test is
failing, the unmount of /test-x-initrd-mount was done *before* the final
step during which systemd remounts+unmounts all the remaining file
systems.
I haven't investigated why this is the case, but the test is a
regression test for https://github.com/NixOS/nixpkgs/issues/35268, which
actually didn't unmount the file system *at* *all*, so really all we
need to take care here is whether the unmount has happened and not
*how*.
To make sure that checking the filesystem state is enough for this, I
temporarily replaced the $machine->shutdown call with $machine->crash
and verified that the file system state is "not clean".

Fixes: https://github.com/NixOS/nixpkgs/issues/67555
Adds:
- gnome-color-manager
- services.avahi
It appears that GeoClue requires its daemon and IIRC has
been default enabled in other distros for a while.
- orca
It's the default screen-reader.
