help
This allows containers, i.e. vservers, to use user namespaces
to provide different user info for different servers.
+
+ When user namespaces are enabled in the kernel it is
+ recommended that the MEMCG and MEMCG_KMEM options also be
+ enabled and that user-space use the memory control groups to
+ limit the amount of memory a memory unprivileged users can
+ use.
+
If unsure, say N.
