Linux encrypted swap

It's one line in /etc/fstab to have swap automatically encrypted, with a fresh keey randomly generated at each boot. Simple (provided you don't also want to have suspend-to-disk).

As for whole disk encryption, I'd recommend just encrypting swap, /home and /var - there really isn't anything worth hiding in /usr/bin (for an Open Source OS !).
