When the raw device rewinds, how do you know that it stands for raw and not rewind? The nr device doesn't rewind. The block device would also rewind, and there was no non-rewinding block device. It was there even in SunOS 3.5 for compatibility. None of the scripts we used used the block device and in fact I think we had problems using the block devices. We should just stop arguing about what it has ment historically and say that "rsa0" is the rewind device and the "nrsa0" is the non-rewind device and not worry about renaming of the device entries. This would match historical use and we'd not have to worry about block vs raw and we won't break all the backup scripts in the world.
