If you specify 'auto' for the filesystem type of a mountpoint, Linux will search through the available filesystem types in finding an appropriate match. The key is to specify potential multiple matches in the order in which you'd prefer they be evaluated. As an example, for a floppy disk, either vfat or msdos might work with a FAT filesystem. You'd want to specify vfat before msdos if you prefer long filenames. The search order is specified by either /proc/filesystems, or, if it exists, /etc/filesystems. The latter superscedes, so if you need to munge sort sequence, specify filesystems in preferred order in /etc/filesystems. I don't know how iso and udf relate to each other, but if they aren't compatible, you should be able to use this method. If either filesystem is compatible with the other (e.g.: you can mount an udp as iso or vice versa), you'll need to try a different trick. Cheers. -- Karsten M.
