OK, read the code yourself as you don't belive me. http://sources.gentoo.org/viewcvs.py/baselayout/trunk/sh/rc-daemon.sh?rev=2441&view=markup But as it's Christmas I'll tell you anyway. A status check will examine every daemon started by start-stop-daemon in the service and check if it's still running by the process name/exec file and optional that it's running on the given pid in a pidfile if specified. If any listed daemons have crashed then the service is stopped and the stopped status is returned. Of course, a non root user can query the status too, but in this case only the init.d/started/service flag is checks as non root users cannot do the above.
