>Description:
        Earlier "mount /dev/cd0d /mnt" mounted file system,
        now it requires explicit hint that FS is "cd9660".
>How-To-Repeat:
        mount /dev/cd0d /mnt
>Fix:
        Restore previous behaviour, please, very few meet UDF that frequently.
        Alternatively, try UDF _after_ ISO 9660.
