Using /mnt/cgroup is definitely wrong. FHS says that /mnt is reserved as a
temporary mountpoint for local use.
If there is a consensus upstream that /sys/fs/cgroup is the right place for
this filesystem, and this is needed in squeeze (rather than just for
systemd) then I think we would add that directory in the kernel package for
squeeze. Otherwise, this is for wheezy (and current experimental) only.
