It's derived from 'ramfs', and it's available in the -ac tree.  'ramfs'
is more of a coding example, but 'tmpfs' is meant for real use - you can
limit it's size, space usage shows up in the output of 'df', it can be
swapped out, and maybe other features as well.

I use devfsd mostly to find out what links it sets. ;-)  Even though
devfsd is small itself, it carries a lot of baggage (library
dependencies & config files) with it.  It's pretty trivial to set the
links I need myself.  Besides, have you ever looked at /dev after
running devfsd?  Almost as bad as before ;-).
