It was removed because with devfs, device entries don't always exist, so an 
unconfigured device is now going to result in ENOENT rather than ENXIO.  The 
example I think was on Alpha which has a /dev/zs0 console on some machines 
and on machines that don't have zs0, log messages about failing to open zs0 
would spam the console.
