i noticed a command called pivot_root, which tantalizingly implies that i can boot to some sort of temporary fs (on an unencrypted partition?), mount the encrypted one (*), then switch to it, but i tried it and it didn't work. i don't mind using a grub floppy to boot. i use debian etch.
You can boot from an encrypted root partition. I think there's some FAQs about it. One uses initrd to perform the initial boot and prompt for passphrase for the encrypted partiton. Once the root partition is mounted it replaces the initial ramdisk.
All this is most easily set up using yaird which creates the initrd for you. yaird supports cryptdisk and LUKS.
