This is aimed at writers of programs that open device nodes, rather
than create them. They would try opening both the devfs and
traditional device names (if applicable), falling back to the
traditional name if the defvs node is unavailale.

OK. I've updated the policy diff to accommodate this (attached), and
filed a bug against policy.
