    I've been thinking about this "change disk now" questions that the
    kernel might need to ask.

    I thought I'd make a character device that simply outputs the question
    to be posed to the user.

    On a text console you just run something similar to

    cat /dev/changemessages &

    On an X display a small tool would present in a requestor anything
    that could come up.

    There might need to be some feedback saying "OK. Done".
