    I've been trying /really/ hard to avoid doing something like that
    because a lot of the time the desired Linux dev name is a
    implementation detail, and a potentially unstable one at that. If
    Linux requires certain devices to have certain names because that is
    how it hooks up clocks (which is the current situation on some
    platforms), then I'd rather have Linux encode a lookup of the
    preferred name, at least until the that particular implementation
    detail goes away.

    As for enumerating devices, I don't think this is a Linux-specific
    thing. In this case it is entirely reasonable to want to say /this
    node/ is the second serial port, and /that node/ is the third, which
    is information needed regardless of the client OS.
