Thanks Matthias for your help (and Jari for the clarification). However I'm still having problems. I make a device-backed aes256-encrypted loop, where the device is a floppy, format the loop device with vfat, then deallocate the loop. Then I put the following in /etc/fstab: /dev/fd0 /home/dsl/crypt1 vfat defaults,rw,noatime,encryption=aes256,noauto,user 0 0 (I've also tried using 'users' plus the guid etc settings as for the fstab entries for my hard drives). BUT when I try to mount as an ordinary user I get: "mount: only root can do that" sudo mount works, but the mount directory has root-only access permissions. This is why I has the wrong notions in my initial post - I'd tried this before. What is going wrong? PS: I'm using a knoppix-based distro __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
