:> What do people think of the udev/hotplug solution vs devfs? At first 
:> inspection, udev appears to be a little more Dragonfly-ish because of 
:> its placement in userland.
:I'd vote for udev (or something like it)

    I think I would prefer udev over devfs.  It seems silly to try to manage
    yet another fake filesystem in the kernel, just look at all the bugs 
    that have cropped up in existing devfs and procfs implementations, not
    to mention unionfs and nullfs!  You'd think we would have learned our
    lesson by now!

    I would definitely prefer a userland demon which performs the work based
    on what the kernels tells it to do.  The kernel can still assign dynamic
    minor numbers for dynamic devices, and that is really the crux of the
    functionality we want to have.
