Hmm, I'm curious how lxc-attach works, since AFAIK that code relies on the same missing kernel support that I describe below. Specifically we need the 'mnt' namespace listed in /proc/self/ns/ - currently kernels only have 'ipc', 'net' and 'uts' namespaces there. What distro and kernel are you using and what files does it show in /proc/self/ns/ ?
