Hehe, I'm the one running a CGROUP=n kernel, so what do I know. Its just
that all this stuff hurts my brain.
Maybe we should just add functionality that requires controllers to be
co-mounted and this extra functionality will then make people co-mount
since you know features.. :-)
I know I've wanted to do that several times, so far I've always resisted
because it looked like pain, but hey, if I can cause more pain somewhere
else and my life gets easier in the long run I might change my mind ;-)
