This daemon is responsible for keeping all the rest of the Condor daemons running on each machine in your pool. It spawns the other daemons, and periodically checks to see if there are new binaries installed for any of them. If there are, the condor_master will restart the affected daemons. In addition, if any daemon crashes, the condor_master will send e-mail to the Condor Administrator of your pool and restart the daemon. The condor_master also supports various administrative commands that let you start, stop or reconfigure daemons remotely. The condor_master will run on every machine in your Condor pool, regardless of what functions each machine are performing.
Section 3.1.2 in the Administrator's Manual has more information about the condor_master and other Condor daemons. See Section 3.9.2 for documentation on command line arguments for condor_master.
The DAEMON_LIST configuration macro is used by the condor_master to provide a per-machine list of daemons that should be started and kept running. For daemons that are specified in the DC_DAEMON_LIST configuration macro, the condor_master daemon will spawn them automatically appending a -f argument. For those listed in DAEMON_LIST, but not in DC_DAEMON_LIST, there will be no -f argument.
