    Yes, unfortunately devfs is exactly that.

    Actually, /dev *IS* just an ordinary collection of files. Yes, it has
    to match the kernel. So do libc, kmod, automount, and a gazillion
    other things. Putting it in kernel space is a quick, dirty hack.

    There is no need for this; it needs to be synchronized with the drivers.

    Do it like PCMCIA, which already supports this kind hot-plugging quite
    nicely thankyouverymuch. Hot-plugging is a heck of a lot more than
    device nodes, which is exactly why so many of the pro-devfs arguments
    are fundamental fallacies.
