Based on what I can gather, cryptoloop is deprecated in the 2.6
kernel, and the new interface (dm-crypt) is not yet fully supported in
userland. dm-crypt is on the TODO list though!
Comment 3 Ian Collier 2004-06-10 08:54:29 EDT
Why is this bug a WONTFIX?  All it requires is the correct patches for
the 2.6 kernel, documented here:

Sure it's deprecated, but it still works, and
 (a) until the userland dm-crypt tools are supplied with Fedora this
is the simplest way to get a crypto filesystem, and
 (b) the FC2 version of losetup is for the 2.4 kernel - it would seem 
stupid not to patch it to be compatible with the 2.6 kernel which comes
with FC2.
