	Given that if /dev/console does not exist you will not be able to
	boot, trying the mfs approach should be a win (or no worse) in
	just about any situation.
	If the filesystem is corrupted to the extent that the the mfs
	setup fails, you haven't lost anything more than before; but if
	the mfs succeeds, you might have a fighting chance of now
	repairing the damage.
	If someone forgot to populate dev, then it makes it more
	interesting to do so ('umount -f /dev ; /dev/MAKEDEV all' ),
	but you still win...
