Correct observation. We could probably change the API today to allow failures, but I would hate to see all the device drivers have to sprout code to try to find an alternative name. But likewise, I am not sure having DEVFS silently append abitrary designators for disabiguation, to duplicate names, is a good idea either, but it may be the least bad idea.
