    Yes, that would work.

    The way I envisioned it, a disc-based /dev would have (for example)
    /dev/cpu being a symlink to $devfsroot/cpu
    Having two hierarchies encoded isn't good.

    I'd much prefer the "/devfs" solution. That means one symlink for folks
    who want to use devfs, and one mountpoint for folks who don't.

    Compare this to how many symlinks we would need to put into /dev in the
    non-devfs case, assuming that people start moving into kitchen sink into
    devfs, and it's just not pretty.
