I know that I could have rolled the files at a specific size, by using the
*max_log_file* attribute as identified in the */etc/audit/auditd.conf*, but
there was no "builtin" for managing auto rotation at the start of a new day
(0000 hrs).
It looks like there is a file called */usr/share/doc/auditd-<**version>*
*/auditd.cron*

Its over 9 years old.

Its a shell script that end up sending SIGUSR1 to auditd. That causes auditd
to rotate the files. But you would also configure auditd to not rotate files by
setting num_logs to 0 in auditd.conf.

Yes. You can also extend the script by sleeping a couple seconds for the
rotation and then rename the file and/or compress it and/or move it to another
directory or partition. Whatever you want to do.
*Finally, if I have '-e 2' as the last control in the
audit.rules file;
will the auditd.cron which executes as service auditd rotate still function
properly?*
The -e 2 makes the rules immutable. Sending SIGUSR1 to the audit daemon just
rotates the files. So, it has no bearing on the matter.
