I've tried every other scheme out there. Nothing else works even
remotely as well. Besides, its not a kludge; there are many devices
for which we have multiple entries in /dev. Tape drives get multiple
device entries depending on density and rewindingness and we don't get
upset. Disk drives get different character and block devices and no
one moans. It all seems plenty unix-like to me.
