Yes, it does. I was proposing that we use a single naming scheme with
conceptual unity and simplicity, instead of having a cryptic "advanced"
naming scheme and a simple "backwards-compatible" naming scheme.
Instead, we could have a single naming scheme in which names get
gradually more complex as you do more arcane things with your machine.

The devfs method reminds me of pasted-on GUIs. As long as you're doing
something simple, you can use the pasted-on GUI, but when you want to
do something more difficult, suddenly you're thrust into the
command-line world where everything is totally different. I think this
is an abomination.

Well, it does look pretty ugly. (I think it's not as bad as Solaris's
/dev/dsk, but maybe you disagree.)

It's an OS that uses something similar to devfs for its devices. I
think you can find more information about it at plan9.bell-labs.com
when it's up.
