<p><b>New page</b></p><div>This is a package provided as part of the [http://debian.tryphon.org Repository] here @ Tryphon. It's intended to automatically start JACK at boot, so your Rivendell daemons can also be started at boot. It mostly works apart from..<br />

= Realtime issue =<br />
<br />
In trying to get this working on my Ubuntu Hardy system, I came across a problem with the realtime option in /etc/jackrc - this fails at system startup, and thus neither Jack nor Rivendell start. It works however once the chosen realtime user is logged in. Hmmn.<br />
<br />
My solution (eventually, after about 6 hours of research!) was to add the following line to the PAM configuration for su in /etc/pam.d/su:<br />
<br />
session required pam_limits.so<br />
<br />
This forces the su command to apply the new realtime permissions when /etc/init.d/jack calls it to run jack as the specified user (who must of course be in the appropriate realtime user group).<br />
