A full disk encryption needs the swap to be encrypted as well. The only solution for getting both the swap and filesystems encrypted using the same key is to put both of them on an LVM itself luks- encrypted using dm-crypt. All my machines have been made this way for *years*, so I know it works damn well ;-) ...And it also allows for hibernateing the system to (encrypted) swap space... That's a pretty fine setup :-) -- Swâmi Petaramesh http://petaramesh.org PGP 9076E32E
