    Apologies, but I'm just now getting a chance to work my way through
    this thread, and I wanted to make a quick comment on this point ...

    The audit container ID (note I said "audit container ID" not
    "container ID") is intended strictly for use by the audit subsystem at
    this point. Allowing other uses opens the door to a larger set of
    problems we are trying to avoid (e.g. handling migration across
    hosts). We would love to have a generic kernel facility that the
    audit subsystem could use to identify containers, but we don't, and
    previous attempts have failed, so we have to create our own. We are
    intentionally trying to limit its scope in an attempt to limit
    problems. If a more general solution appears in the future I think we
    would make every effect to migrate to that; keeping this initial
    effort small should make that easier.
