You must enable "RSBAC own logging" in kernel config, then the buffer will 
appear as /proc/rsbac-info/rmsg. This logging source is by default only 
accessible for the system roles "security officer" and "auditor", "system 
role" is set for user 400.

You can use the rsbac-klogd from the admin tools to write it all to disk. 
The rklogd will setuid to 400 (or optionally another id) first.
