Seriously. If we're going to have devfs, let's do it right rather than half-hack it in /proc. The /proc stuff has all the problems of a super-naïve implementation of devfs, and unlike Richard's devfs doesn't have even a hacky way around the problems.
Now devfs is in the kernel, so let's just work out the kinks and make it do what we need it to do.
