I think splitting out services that are useful in environments without
an init system installed, such as sysusers, might be useful.

Possibly also tmpfiles, but without an init system nothing would start
the service and it would have to be invoked manually.  Maintainer
scripts might use it though to setup directories in /var/lib or similar
locations.

I think we should agree that using them is okay before considering to
split them into a separate package from systemd.

There is already an alternative implementation for tmpfiles.d:

I don't know more than that it exists though.
