[ClusterLabs] Trouble starting up PAF cluster for first time

Since I'm installing PAF using `apt-get install resource-agents-paf`, I would expect that it being packaged for Debian/Ubuntu would follow the standard of that platform.  Would it be possible for the APT packager to add a patch to change this default?  Thanks for explaining this - I've been using /var/run/postgresql myself for so long that I forgot /tmp was the upstream default...

It would be great if there were a way for it to log more information back to Pacemaker about what exactly it's executing as it does so, even if this required a non-default debug configuration.  I guess either way that Pacemaker doesn't have any direct awareness of what commands are being executed through the resource agent so it's not a job that Pacemaker could do itself.

Thanks for the help!
