View source for Rivendell daemons

Rivendell has several daemons that run in the background helping things work.  

The daemons can either be started during system boot up, via the /etc/'''init.d''' script, or they can be started as needed by the Rivendell programs using [http://en.wikipedia.org/wiki/Pluggable_Authentication_Modules PAM].  In the latter case, where the daemons are started as needed, the '''pam_rd''' PAM module can be used to ensure any old instances of the daemons are cleared out when a user logs in.

The order the daemons start is important, as they depend on one another.  Here they are listed with the top most items started first:

* 1) '''jackd''' ['''optional'''] (the jack audio connection kit daemon which allows for routing of audio from one application to another, only used if using the jack audio subsystem)
* 2) '''caed''' (the core audio engine daemon, which reads the audio files and plays them to the sound card)
* 3) '''ripcd''' (the rivendell interprocess communication daemon)
* 4) '''rdcatchd''' (a daemon to run batch jobs capturing and sending out audio)
* And then finall the Rivendell Applications can start (ex: rdairplay, rdlibrary)
