Bits of devfs also live on in sysfs. So devfs wasn't a bad initial idea IMHO, but
we had to do one more (incompatible ...) iteration to figure out why we didn't
like it.

Furthermore, I'm pretty sure there's a snowball's chance in hell that we'd have
ended up with the current pretty cleaned up hardware/system ABI _without_ devfs.
So it was a necessary pain.
