I'm late in the conversation, but "what Steve and Paul said".  A number
of discussions have already happenned concerning this idea and the goal
is to have auditd be able to run pretty much seamlessly inside a
container without influencing or compromising the auditd running in the
parent namespace(s).  From what we have discussed, it appears most
likely that auditd will be anchored one per user namespace.
