Having separate labels on the unit file is not just for "user" domains.   It
is also for system domains, for example NetworkManager_t is allowed to start
the following services.

 sesearch -A -s NetworkManager_t -p start
Found 5 semantic av rules:
   allow NetworkManager_t nscd_unit_file_t : service { start stop status
reload } ;
   allow NetworkManager_t ntpd_unit_file_t : service { start stop status
reload } ;
   allow NetworkManager_t pppd_unit_file_t : service { start stop status
reload } ;
   allow NetworkManager_t polipo_unit_file_t : service { start stop status
reload } ;
   allow NetworkManager_t dnsmasq_unit_file_t : service { start stop status
reload } ;

I rely on Dominick and Miroslav to get Fedora changes/fixes upstream.

Could you guys take care of getting systemd policy upstream.
