Why device names instead of labels or UUIDs?

noauto?????

I understand why this is ro; why then is /boot rw?

What does nodev mean? (My google fu must be lacking.) Is "Do not

just extra security so that a rogue app doesn't try to create a

Seems to me that this whole exercise is to ensure that /dev is in
it's own partition.
