    I would have thought CDs and DVDs would work the same as hard drives
    (working from the outside in).

    So the space is set aside for memory swapping, thus "swap", right? And, as
    you say, the os won't store any permanent files there. The os can then dump
    RAM buffers into it in whole, starting right at the beginning of the swap
    space and moving forward, without worrying about stepping on any files.

    At installation time, where Nick (Nick being the guy who started this
    thread, back in the day) is right now, right?
