And further to the point, right now, we don't want events from inside the 
container going to the system audit daemon. It potentially has no idea what a 
pid, network, uid, gid, or hostname maps to. These have to be resolved inside 
the container and then aggregated at the system daemon or datacenter 
aggregator.
