/kind bug
What happened:
All cadvisor container_fs_* stats are 0, except a few without pod/image labels which I assume are for the root cgroup:
What you expected to happen:
Have these stats return right values..
How to reproduce it (as minimally and precisely as possible):
As far as I can tell, this should happen on a fresh install too.
Environment:
kubectl version): 1.8.1
