Hi,
   I am looking at adding an option "-G group" to sdpd(8) to allow members
of the specific group to modify the database, so that for instance you
don't need root privileges to run programs which register a service and
wait for bluetooth connections.

   Is it ok to cache a gid returned from getgrnam(3) during the setup, or
should I check it on each open, in case it changed?
