Comment 8 for bug 1392176

The movement of existing tasks to the child cgroups created by cgmanager/systemd must be avoided as far as I can see.
If the additional cgroups are for LXC containers, the containers and the tasks spawned within them alone can reside under the children cgroups. Why move the existing tasks into them, when they are not going to benefit from it ? If this can be done there would be no need to avoid having to mount cpuset controllers; they can very well be there.
