Subject: [PATCH] add a bit more boiler plate code. Right now I just touch a
 file in $STATEDIR, maybe this should include the path to the Nix store and a
 sanity check should be added to make sure that if we check the file in
 $STATEDIR that it is indeed from an instance of the service that we want to
 start. This adds complexity, because how should we deal with the situation of
 they are not equal.

TODO: add a "status" command, or a "version" command, which displays which
service is currently registered with the system as "running"
