The problem is in the bluetooth sysv script. As you probably have noticed, 
for most services this is no problem:

	[root at server1 root]# service gpm status
	gpm is stopped
	[root at server1 root]# echo $?
	3
	[root at server1 root]# service ntpd status
	ntpd (pid 12400) is running...
	[root at server1 root]# echo $?
	0
	[root at server1 root]# service bluetooth status
	bluetooth: unrecognized service
	[root at server1 root]# echo $?
	1
But
	[root at server1 root]# service bluetooth status
	hcid is stopped
	sdpd is stopped
	hidd is stopped
	[root at server1 root]# echo $?
	0

If you look inside the script, you can see that the return code is not 
being captured. Which one should it capture and exit with ?

For other services, where there's only one process to check, it's quite 
simple. Here the solution could be to return 0 if all services are 
running. (ie. take the sum of the return codes)

If you think this is a defect and you expected something else. Open a 
bugreport in bugzilla and then do a support call and point to this 
bugzilla entry.
