I was under the impression that each i-node in tmpfs consumed a fair 
amount of space, making it a bad match for things like /dev which have 
very many i-nodes but no actual files.  (Well, I've seen glitches on 
ancient systems where /dev/null got turned into a regular file, leading 
to amusing messages about "/dev/null: no space left on device"...)
