Thanks! The trouble is that I don't know how to encrypt home/knoppix, I know how to do a container but I don't know how to "link" it to home/knoppix, either where I have to store this AES container PS I had a trouble in etc/fstab, sdc2 wanted to mount on /, I don't know why ! I fixed that, but sdc2 still doesn't appear anywhere at boot up, I still have to mount it by a command line.
