basically that page, which is an archive of an email i sent some time ago,
says:

1. there's a patch [1] that allows linux-vserver to work with user namespaces
   enabled (where "work" means linux-vserver and lxc both appear to function
   correctly based on my limited test cases; the lxc failure mentioned in the
   email was later addressed by a herbert-provided pid namespace fix that
   should be integrated into the latest linux-vserver patch for 3.14).

2. the patch is unsupported by any and every party: upstream, linux-vserver,
   and myself. if it works: great. if not: sorry.
