Broke in terms of what? Size? Looks okay to me.... datestamp, well,
maybe.

I was asking Will actually, since that would explain the 0-size /dev.

Linus was right about what? devfs?

Nope, got me there ;))

So you don't think it's good piece of forward planning ? ;)

I'm not really sure what the semantics ought to be for a virtual
filesystem. Copying the behaviour as if it were 'real' would be nice,
but strange. It's kind of more like an atom in a quantum state - you
