As you correctly mentioned, auditd worked by adding audit and audit_control to
the capability section of flask/access_vectors.
Noticed that audit.log shows "avc: denied" kernel events that are not reported
in messages. Are these suppressed by the dontaudit rules in the policy?
Thank you for your help.

Off-by-one bug in checkpolicy, fixed after FC3, but shouldn't matter as
you only need two permissions here.

I've sent (via separate email) a copy of our current
policy/flask/security_classes, policy/flask/access_vectors,
policy/domains/program/auditd.te, and
policy/file_contexts/program/auditd.fc, so you can at least try those to
see if they resolve your issue for auditd (and they shouldn't impact
anything else). If that resolves your problem, then feel free to stay
with FC3 until FC4 is out (schedule says June 6).
