Thank you The one way I did it is as follows: 1. Create a file to hold your filesystem 2. losetup it as a loopback device using encryption, I used loop-AES 3. create a filesystem and put the data on that filesystem 4. losetup -d to disconnect the loop and burn this file as an iso image growisofs -Z /dev/dvd=filesystem-file This way you have it and all you have to do is: losetup /dev/loopX /dev/dvd .... with the rest of the crypto options you used to create it. Then just mount loopX and you are all set. -- Nasko Oskov "A hacker does for love what others would not do for money."
