Instead of mounting a new filesystem, revert to doing a `rw` bind. However do not make `/` `rshared`, just `/var` as that is where we expect filesystems to be mounted for persistence. Also only make the actual container rootfs writeable, not the whole directory. Signed-off-by: Justin Cormack <justin.cormack@docker.com>
