I guess I am just lucky, because that hasn't failed me in years. I think I can live with that for now. >> How do you get a file-backed encrypted filesystem to work under >> Linux 2.4.24? Looking at the (lack of) answers to my question, I gather there is no clear-cut answer, or rather that the answer is "you don't".

And, just wondering -- if loop-AES works so much better, why hasn't it been included in the kernel? --J.
