autodev: switch strategies (v3)

Do not keep container devs under /dev/.lxc. Instead, always keep them in a small tmpfs mounted at $(mounted_root)/dev. The tmpfs is mounted in the container monitor's namespace. This means that at every reboot it will get re-created. It seems to me this better replicates what happens on a real host. If we want devices persisting across reboots, then perhaps we can implement a $lxcpath/$name/keepdev directory containing devices to bind into the container at each startup. Changelog (v2): don't bother with the $lxcpath/$name/rootfs.dev directory, just mount the tmpfs straight into the container. Changelog (v3): Don't create /dev if it doesn't exist Signed-off-by: Serge Hallyn <serge.hallyn@ubuntu.com> Acked-by: Stéphane Graber <stgraber@ubuntu.com>
