Until now nixos only delivered the latest zfs release. This release is often not
compatible with the latest mainline kernel. Therefor an unstable variant is
added, which might be based on testing releases or git revisions.
fixes #21359
/etc/hostname is the file used by hostnamectl(1) and the
org.freedesktop.hostname1 dbus service (both provided by systemd) to get
the "static hostname". Better provide it so that users of those
tools/services get a proper hostname.
An example of an issue created by the lack of /etc/hostname is that the
bluetooth stack on NixOS identifies itself to peers as "BlueZ $VERSION"
instead of the hostname.

Changes v1 -> v2:
* ensure /etc/hostname ends with a newline
Now the tracking works with aggregated devices on aggregated devices.
So container with physical device where the device is put in a bond
which is the basis for a bridge is now handled correctly.
Test that adding physical devices to containers works, find that network setup
then doesn't work because there is no udev in the container to tell systemd
that the device is present.
Fixed by not depending on the device in the container.
Activate the new container test for release
Bonds, bridges and other network devices need the underlying not as
dependency when used inside the container. Because the device is already
there.
But the address configuration needs the aggregated device itself.
Using types.str doesn't work if you want to mkBefore/mkAfter across
different module definitions, because it only allows for one definition
for the same priority.
This is especially useful if you deploy Hetzner machines via NixOps,
because the physical specification already defines localCommands.

See #18319 for details. Starting network-online.target manually does not
work as it hangs indefinitely.
Additionally, don't treat avahi and dhcpcd special and sync their systemd units
with the respective upstream suggestion.
Systemd upstream provides targets for networking. This also includes a target network-online.target.
In this PR I remove / replace most occurrences since some of them were even wrong and could delay startup.
A new internal config option `fileSystems.<name>.early` is added to indicate
that the filesystem needs to be loaded very early (i.e. in initrd). They are
transformed to a shell script in `system.build.earlyMountScript` with calls to
an undefined `specialMount` function, which is expected to be caller-specific.
This option is used by stage-1, stage-2 and activation script to set up and
remount those filesystems. Options for them are updated according to systemd
defaults.
