From source code of audit RPM released with Fedora 15 (http://download.fedora.redhat.com/pu.../source/SRPMS/
), I understand that :
- log rotation is indeed handled internally by the auditd daemon
- there is currently no compression after log rotation
So your audit.X.gz are not generated by auditd, but by something else (a customized script ?)
I would suggest you not to disturb the auditd daemon with additionnal mechanisms.
Concernening the myriad of files generated, if you still have them after getting rid of the .gz files, you should post the content of /etc/audit/auditd.conf file.
