Since the old/default behavior is on its way out, I didn't invest time
in fixing that. Also, some of the properties that make
cgroup-namespace simpler are only provided by unified hierarchy (for
example: a single root-cgroup per container).

Does the new sane cgroupfs behavior even have a single real world user?
I always thought it isn't stable yet.

Linux distros currently use systemd v210. They don't dare to use a newer one.
Even *if* systemd would support the sane sane cgroupfs behavior in the most recent
version it will take 1-2 years until it would hit a recent distro.

So please support also the old and nasty behavior such that one day we can run current
systemd distros in Linux containers.
