perhaps obvious question: auditd and setuid/setgid?

[John Jasen]

I'm currently testing auditd with rules for setuid or setgid binaries on
the system.

I currently maintain the list via find, and pushing the results to a
audit.rules file.

I'm hoping there's a cleaner way, perhaps by triggering on the
appropriate syscall -- but have not discovered it.

Is there an easier method?
