I think at this moment, systemd init script is way too much 'distro-oriented'
to make it usable from default package installation.

(We do not ship SysV nor Upstart script either)

It's probably for discussion how the 'startup' should be configurable,
where to put configurable parts for startup script and how to handle
dependencies.  Currently I do not see big use for the currently proposed patch
 (I think you are repeating here when initially systemd
automatically mounted all filesystems from fstab...)
