Largely orthogonal.

This discussions is hard because Paul has appropriated our term for
the user space aggregation of all of the pieces (a container) using
for some subset of that, so my apologies if there is some confusion.

There are a few issues with the filesystem part of Paul's patchset
that currently do not allow for nested containers.

Generally the Paul's container filesystem work provides a generic
framework for resources controls that we want in addition to the
namespaces.  I'm not at all certain I like the filesystem interface
to user space, but having a common interface to user space and helper
code to use it for all of the resource controls makes sense.

I think there is a little more like a user space visible identifier
that is also interesting.
