Do we need to consider the case where children tasks are actually in
*sibling* cgroups?

Maybe it would make sense to map cgroup names into tags in dump and
restore just like the ext-mount support does...

I'm really wondering if it wouldn't be easier to handle the cgroup
hierarchy through external plug-ins, considering each container
solution seems to have their own idea of how to manage cgroups.
