While testing v212 I found a problem with cgroup management introduced by a commit[0] in systemd. The commit prevents any other programme from creating a directory in /sys/fs/cgroup. When amd tries to set up its "mgr" directory it hits[1]. Then amd as a revenge[2] destroys all the contents of the directory. The easiest way to overcome this problem is to revert the systemd patch on the tizen branch. However, this might have some long term consequences. I don't know much about amd and the way/reason it uses cgroups so I can't devise any solution. As far as I remember there have been plan to forbid any programme other than PID#1 systemd control cgroup hierarchies.
