I suspect Steve is mixing up AUDIT_CONTAINER_OP with AUDIT_CONTAINER_ID, confusing the fact that they are two seperate records. As a summary, the suggested records are: CONTAINER_OP audit container identifier creation CONTAINER audit container identifier aux record to an event and what Paul is suggesting (which is fine by me) is: CONTAINER_OP audit container identifier creation event CONTAINER_ID audit container identifier aux record to an event Steve, please indicate you are fine with this. > paul moore - RGB -- Richard Guy Briggs Sr. S/W Engineer, Kernel Security, Base Operating Systems Remote, Ottawa, Red Hat Canada IRC: rgb, SunRaycer Voice: +1.647.777.2635, Internal: (81) 32635
