The pach is: implement -M to support skip mounting certain controllers
So you need to start cgmanager with "-M cpuset" to get the behavior you
are looking for.
The changelog entry said:
This doesn't change the default, so may not suffice for powerpc,
but at least offers a workaround. (LP: #1392176)
So it is a starting point and gives you a workaround. It seesm to me
that this is something that should be configurable in the kernel.
It also seems worthwhile for cgmanager to watch for cpu hotplug events
and do something when it gets those. But exactly what it should do
and how this is best implemented is not clear to me.
