force audit log rotation?

[Dr. Michael J. Chudobiak]

Hi all,

How do I force an audit.log rotation in a systemd world (F16)?

"service auditd rotate" no longer works, of course.

locate auditd.cron
cp /path/to/auditd.cron /etc/cron.daily/auditd.cron

This seems to work for me:

systemctl kill -s SIGUSR1 auditd.service

Didn't work for me,

but I modified the auditd.cron daily job to:
mv /var/log/audit/audit.log /var/log/audit/audit.old
touch /var/log/audit/audit.log

Now as I'm not a bash guru,
If I could figure a way to date audit.old*

Thats not going to work because auditd is not going to like the
permissions on the new audit.log.

Really though it works for me:

I think that auditd.cron needs to be edited:
