As you're aware, as of F15 we changed our default init system from
sysvinit to systemd. But we have lots and lots of packages with
daemons, and not all have thus far been migrated. Some maintainers
haven't responded, some are too busy, some aren't sure how to go about
it. In many cases, unit files have been posted by helpful individuals
(Thanks Jóhann B. Guðmundsson!) but they're not yet in the packages.
If you're a Provenpackager, check out these two tracking bugs:

And have a look at:
Look through, find something that looks manageable, and volunteer.
Most maintainers will be receptive, I think, but remember, offer/ask
before jumping in. If they're not responsive, we'll cross that bridge
It would be better to walk through this list  which was designed
specifically with PP participation in mind as discussed with Toshio
during the F16 development cycle.
Just add your name to Proven Packager and flag it passed when you have
packaged the relevant component.
