Interesting... smells buglish.

# grep nagios_group nagios.cfg
nagios_group=nagios

# ps -eo pid,user,rgroup,command | grep nagios

27347 nagios   nagios /usr/local/nagios/bin/nagios -d
/usr/local/nagios/etc/nagios.cfg

# vi nagios.cfg

# grep nagios_group nagios.cfg
nagios_group=nagcmd

# /etc/init.d/nagios restart
Running configuration check...done
Stopping network monitor: nagios
Waiting for nagios to exit . . done.
Starting network monitor: nagios

# ps -eo pid,user,rgroup,command | grep nagios

32016 nagios   nagcmd /usr/local/nagios/bin/nagios -d
/usr/local/nagios/etc/nagios.cfg

I see the change here -
-rw-rw-r--    1 nagios   nagcmd     829161 May 22 07:25 status.dat

But not here -
prw-rw----    1 nagios   nagios          0 May 22 07:26 nagios.cmd

I also see that in base/nagios.c that nagios drops privs to nagios_user
and nagios_group before calling open_command_file (which doesn't seem to
specify a specific group) so I would expect it to be group nagcmd.
Clearly I'm missing something. It's unintuitive behavior at the least
but it seems more than that IMHO. Can anyone test with a 3.x install?
