    : Actually, this is exactly what my "supermount" patches do (available
    : for 2.0 on linux.dcs.ed.ac.uk in /pub/linux/supermount!). It provides
    : truly transparent removable media support for both floppy and cdrom.

    : There are a couple of problems with the current release. Only msdos
    : and iso9660 filesystems are supported, and the door locking on 2.0
    : kernels means that you can't change disks on cdroms for many drives
    : which were OK on 1.2. The 0.5 releae of supermount is in progress and
    : under testing, and will address these deficiencies.

    My concept for changing data CDs is:
    say "umount /CD"
    watch the tray coming out
    fetch the old CD
    put down the new CD
    say "mount /CD"
    watch the tray slipping in
    Realized, years ago. You even can let it do by a robot arm. Standard Linux.
