that sounds great: Well done!

BTW: Do you know the kernel parameter for cgroup namespaces? The 
     kernel config knows only about CONFIG_NAMESPACES, UTS_NS, IPC_NS,
     USER_NS, PID_NS and NET_NS. I know, there are cgroup namespaces,
     but what is the configuration parameter? I'm just wondering...

Best regards

Dirk
