Are we sure we want to support Group= at all? Instead, I'd expect the
setuid activation helper to 

 - change to primary group of the User
 - init supplementary groups of User; e.g. user 'hwdaemon' may be a
   member of the 'disk' group so that user can access raw disks;

which is similar to how su(1) and sudo(8) works IIRC. Having an option
to specify the Group seems.. well, I don't get the it.
