Bug description:
  I'm trying to get docker-1.8.2-rc1 to work on snappy, while doing so I
  got this apparmor denial:

  Sep 10 09:12:35 localhost.localdomain audit[1320]: AVC
  apparmor="DENIED" operation="mount" info="Failed name lookup -
  disconnected path" error=-13 profile="docker_docker-
  daemon_IAUSSaDNVTJR" name="/run/docker/netns/6901f2b6dd4c/" pid=1320
  comm="exe" srcname="" flags="rw, bind"

  and trying to chase it I got:
  http://paste.ubuntu.com/12341612/

  so docker is trying to issue this mount: 
  syscall.Mount("/proc/self/ns/net", /var/run/docker/netns/5b9b1ba4437b, "bind", 4096 (syscall.MS_BIND), "")

  from https://golang.org/pkg/syscall/#Mount
  func Mount(source string, target string, fstype string, flags uintptr, data string) (err error)

  which is denied as if there wasn't a source?
