(Sorry, I had intended AUDIT_CONTAINER for the first in that paragraph
above.)

Ok, I had shortened the record field name to "contid=" to be unique
enough while not using too much netlink bandwidth. I could have used
"cid=" but that could be unobvious or ambiguous. I didn't want to use
the full "containerid=" due to that. I suppose I could change the
field name macro to AUDIT_CONTID.

For the one that starts the container, I'd prefer to leave the name a
bit more general than "_INIT", "_START", so maybe I'll swap them around
and use AUDIT_CONTAINER_INFO for the startup record, and use
AUDIT_CONTAINER for the syscall auxiliary record.

Does that work?
