would prefer to emphasize their differences. A replacement for cryptoloop means you must support cryptoloop's on-disk format.


Do you dislike the cryptoloop format?

What if you wanted to take a disk that was used with dm-crypt, and copy it
to a file on a larger filesystem? Would the data now be inaccessable
because it's not in a format mountable by a loop driver?


Remember we are talking about two -totally different- drivers here.

I can't take my reiserfs data, copy it to a file on a larger filesystem, and then mount it with ext3. And that's a good thing.

dm-crypt should not be constrained by cryptoloop, and vice versa.
