    David Balazic:

    Sorry I still have Not caught up on all this thread, yet I can add:

    > How should I make the image ?
    > Remember, it is a multisession CD ( has two sessions ).

    I'm curious to know how you answered that question, because:

    I see this UDF disc image did Not arrive here in a usable form:

    $ logger 1
    $ sudo mount -r -t udf -o loop=/dev/loop0 udf.iso /mnt/loop0
    mount: wrong fs type, bad option, bad superblock on /dev/loop0,
           or too many mounted file systems
           (could this be the IDE device where you in fact use
           ide-scsi so that sr0 or sda or so is needed?)

    I haven't yet seen you report uname -msr of 2.6.7 or better.

    I missed how Ben F's suggestion of mount -t udf -o session=$n worked
    out.

    The David Burg & Gerrit S input I have not processed.

    Etc.

    Link rotted away by now, I think.
