In the thread I quoted, G-K H mentions that /sys/fs/cgroup would be a tmpfs.

I remember discussions, where to mount the cgroupfs [1], some while ago,
and /sys was among the recommendations.  More importantly though, it was
said that we should see what the kernel folks do.

With the aforementioned patch, the kernel maintainers have more or less
answered the question and as already said, this patch will land in .36
and the Debian kernel for that matter.

Do you see any problems, why this patch should not be in the .32
(squeeze) kernel?
