Oh yeah, it's horrifying. There was something going on a while ago but I couldn't get hold of Eric Paris. We probably should resurrect that patch. As for delegating to namespaces, I'm not exactly sure what to do. At least for now, it could be an acceptable trade-off to delegate the subdirectory with some limits on the number of cgroups / depth of hierarchy / whatever. That said, I'm not really fond of the idea. It isn't likely to work seamlessly. The root cgroup is special anyway and I don't really like the idea of putting NS related stuff directly into cgroupfs.
