As I've said before you'll need to be pre-processing these files
anyway, so either the class gets *even more* logic or you just deal
with it.  Over time more and more upstreams will get systemd support
so we'll be carrying overcomplicated logic for no reason.  We're
really just talking about one conditional and a sed call here.
