I've used the i-kernel for years now, but I'm having trouble installing it
on a laptop I'm using.  I patched the standard 2.2.18 kernel with the
2.2.18-3 i-kernel patch, compiled and booted and created a file to store
the data with no problems, but:

$ losetup -e serpent /dev/loop3 ./.cryptfile
Unsupported encryption type serpent

I've tried the obvious spelling variations ('serpent', 'Serpent', etc.)
and tried using AES instead, tried recompiling util-linux (2.10p) and
reinstalling mount, umount, losetup.  No joy.  All the encryption stuff
is compiled into the kernel (not as modules), and in my syslog is the
following

[...]
Aug 11 19:23:34 tosh kernel: cryptoapi: Registered rijndael (16)
Aug 11 19:23:34 tosh kernel: cryptoapi: Registered rijndael-cbc (65552)
Aug 11 19:23:34 tosh kernel: cryptoapi: Registered aes (18)
Aug 11 19:23:34 tosh kernel: cryptoapi: Registered aes-cbc (65554)
Aug 11 19:23:34 tosh kernel: cryptoapi: Registered serpent (7)
Aug 11 19:23:34 tosh kernel: cryptoapi: Registered serpent (65543)
[...]

I looked, and /proc/crypto{cipher,digest} are there, with aes, aes-cbc,
serpent, serpent-cbc, etc.  I'm using progeny debian 1.0.  I did remember
to point the util-linux configure script at the right kernel headers.

Do I need a more recent util-linux?  I coulnd't see anything in the
(util-linux) changelog that related to that.

Thanks for any help


John
