So, it were just being part of the isolated domain thing, it would make sense, but as a separate flag which isn't hierarchical, it's weird to put it there. > Also, I wonder if a proc/sys interface might be problematic for certain > middleware that is substantially based on using cgroups.

This is fine for something which benefits from hierarchical organization but it is weird to require building cgroup hierarchy for straight-forward system-wide features. Thanks. -- tejun
