The problem here is that the kernel has no concept of a "container", and I
don't think it makes any sense to add one just for audit.  "Container" is a
marketing term used by some userspace tools.

I can imagine that both audit could benefit from a concept of a
namespace *path* that understands nesting (e.g. root/2/5/1 or
something along those lines).  Mapping these to "containers" belongs
in userspace, I think.
