But it's a real stretch to say that providing those systemd units upstream
makes a serious difference in maintenance overhead for distros.  Either
systemd units, like upstart jobs, are easy to write once and require minimal
ongoing maintenance; or they aren't and that's a pretty big strike against

Furthermore, the kinds of things that *will* require changes to job/unit
files - such as dependency changes - are very likely to be driven by distros
in response to local integration needs.

So I don't buy the claims that systemd units upstream are somehow a
significant advantage of systemd over upstart.
