@ggzengel Is this a typo or are there instances in which that service name is actually used? If they are both in use in different places to refer to the same thing, we might want some kind of way of doing either/or. If systemd does not support that, then maybe via some distinction detected via autotools.

Does systemd allow you to specify multiple services like this? Also, please squash the commits which you refresh this.

@ryao First I thought it was a typo, because I use ubuntu and debian. But after some investigation I found that both variants are used.
So I put both services inside.

@behlendorf They use plural in there description. So it should work.
I'm just learning to use git with eclipse. So I will do squash.
