Unfortunately, this is not something that maps well to systemd. It would
require a systemd to run a script that parses the sysconfig file and
start all the tinc daemons. Systemd will then put all those daemons in
the same control group and won't recognize something is wrong if only
one of the daemons fail. So backwards compatibility with the old way Red
Hat did it is not really the way to go.

That one has the drawback that it only starts one tinc daemon, and you
have to edit the service file to specify the netname.
