Generically we can use subsystem now for the individual pieces without
confusing anyone.

I really don't much care as long as we don't start redefining
container as something else. I think the IBM guys took it from
solaris originally which seems to define a zone as a set of
isolated processes (for us all separate namespaces). And a container
as a set of as a zone that uses resource control. Not exactly how
we have been using the term but close enough not to confuse someone.

As long as we don't go calling the individual subsystems or the
process groups they need to function a container I really don't care.

I just know that if we use container for just the subsystem level
it makes effective communication impossible, and code reviews
essentially impossible. As the description says one thing the
reviewer reads it as another and then the patch does not match
the description. Leading to NAKs.

Resource groups at least for subset of subsystems that aren't
namespaces sounds reasonable. Heck resource group, resource
controller, resource subsystem, resource just about anything seems
sane to me.

The important part is that we find a vocabulary without doubly
defined words so we can communicate and a small common set we can
agree on so people can work on and implement the individual
resource controllers/groups, and get the individual pieces merged
as they are reading.
