Hmmm?  You were talking about the old hierarchies?

I have no idea what you're on about.  If the outer system uses unified
hierarchy, the inner system should use that too.  If the outer system
doesn't use unified hierarchy, namespace support has never existed,
and even if it did, the inside could never pick and choose controllers
independent from the outside.  If the outside is co-mounting cpu and
cpuacct, the inside is either also doing that or not mounting either.
