'ns' is one of functions of cgroups like such as devices, memory,
cpu, etc. and it is enabled if you mount cgroup without any options
that Tony is doing.

Oh, you don't enable 'ns', so yes, things go fine in your environment.
I added the 'ns' controller as another mount poiint, and weirdly
everything still worked. It was only when i rebooted and mounted
everything at the same mount point that it stopped working. I'll
investigate why this is & try and come up with a fix for 'ns'
