no logging of successful events?

[Brian LaMere <brianl@clinicomp.com>]

with the following auditd.conf and audit.rules, we generate MASSIVE logs
very quickly.  I don't care about successful audit events; I'm not
required to log them, and there's no way I could have the space for a
year's worth anyway.  So...why is it that "LIST_RULES: exit,always
success!=0 syscall=open" doesn't disregard the successful calls?  I can
still see them if I do an aureport.

The logs are simply too massive to keep; if I set the max_log_file to
much higher than 50 with 99 logs, an aureport takes eons.
Unfortunately, it needs to be that high to save even a day's worth of
logs when they're running certain programs.  Any suggestions?
