CDfs 2.6.12

CDfs is a file system for Linux systems that `exports all tracks and boot images on a CD as normal files. These files can then be mounted (e.g. for ISO and boot images), copied, played (audio and VideoCD tracks)... The primary goal for developing this file system was to `unlock information in old ISO images. For instance, if you have a multisession CD with two ISO images that both contain the file a, you only see the file a in the second session if you use the iso9660 file system: [root@k6 /root]# mount -t iso9660 -o ro /dev/cdrom /mnt/cdrom [root@k6 /root]# ls -l /mnt/cdrom total 2 -r-xr-xr-x 1 root root 2 Aug 8 19:16 a -r-xr-xr-x 1 root root 2 Aug 8 19:19 b If you mount the CD with the cdfs file system, you get the two sessions as files: [root@k6 /root]# mount -t cdfs -o ro /dev/cdrom /mnt/cdfs [root@k6 /root]# ls -l /mnt/cdfs total 33389 -r--r--r-- 1 ronsse ronsse 33503232 Aug 8 19:36 sessions_1-1.iso -r--r--r-- 1 ronsse ronsse 34121728 Aug 8 1999 sessions_1-2.iso These files can then be mounted loop back: [root@k6 /root]# mount -t iso9660 -o loop /cdfs/sessions_1-1.iso /mnt/loop1 [root@k6 /root]# mount -t iso9660 -o loop /cdfs/sessions_1-2.iso /mnt/loop2 and the file a can be accessed in both sessions [root@k6 /root]# ls -l /mnt/loop1 total 9889 -r-xr-xr-x 1 root root 10104236 Aug 8 17:34 a [root@k6 /root]# ls -l /mnt/loop2 total 2 -r-xr-xr-x 1 root root 2 Aug 8 19:16 a -r-xr-xr-x 1 root root 2 Aug 8 19:19 b The file system also allows you to access data on faulty multi session disks, e.g. disk with multiple single sessions instead of a multi session (for instance created with mkisofs without the proper -C parameters).
