    I'd make them different types of events. I'd also prototype it up to
    see how bad things get.

    In the long term, we want CAM to be newbus.

    However, in the long term we'd also like to move away from doing
    things to devices, and more towards doing things on the resources they
    provide to the system. When a network interface appears, we should
    use that event, not that a driver attached.

    The simple devd detach/attachment stuff we do now gets us a lot of
    bang for the buck, but there are limitations.
