CDFS
I found out another OS called cdfs. The installation is quite simple: download it from http://www.elis.rug.ac.be/~ronsse/cdfs/, then patch the kernel source. It is also possible to just type make at cdfs directory; insert the module and, depmod and modprobe it. You have a new filesystem!
Once done, update /etc/fstab adding the following line for example:
/dev/hdc /media/CDFS cdfs user,noauto,exec,ro 0 0
(Don’t forget “cdfs” at the 3rd column).
Mount /media/CDFS (of course you should have created that directory) and, instead of listing the CD content, you will see the image files.
[swobodin@swobodin ~]$ ls /media/CDFS/
sessions_1-1.iso
[swobodin@swobodin ~]$
It is very useful when you want to copy a CD without having to dump it; furthermore, you can get a full information about the mounted CD:
cat /proc/cdfs
