Ok, how about we make the system-cgroup-dir configurable in
/etc/lxc/lxc.conf? So if you have
lxc.system-cgroup-dir = /machine
then root-created containers will end up in /machine (or, if you're
already nested under /lxc/m1, then /lxc/m1/machine). If that is
unset or /, then you're placed in root cgroup. If you're not
root, then you end up under your current cgroup (assuming you
have rights to create them, which you won't for some)
Does that seem reasonable?
