Yes, it's bloated when it comes to loop-AES alone and confusing, but
it offers a promising alternative. Look into it. Nobody I know uses
suspend modes whatsoever, it's just another linux fetish, nothing
scary ;P


Apart from that, I've managed to set up an initrd for my backup
machine; you ssh into it and set up the loop device and it just goes
on booting the encrypted system; nothing but a proof of concept,
unrelated to tux on ice.

That's what I meant, see
http://mail.nl.linux.org/linux-crypto/2008-01/msg00040.html

Did that mail get through? I did not receive a copy.

This could be done easily, in theory. I haven't tinkered with UUIDs /
labels at all (just don't need them at the moment), but it should be
a piece of cake adapting build-initrd.sh accordingly.

I'd go for the initramfs options, it's easier to adapt. Why don't you
try tweaking the script yourself? It's fun. Additionally, when it
comes to certain aspects this mailinglist seems like a one-way road.

I'm happy with my standard ASCII 40+ char passphrase ;p
