Re: Bullshit story
Actually it is possible to boot the whole encryption way..
There is an option in /etc/default/grub called GRUB_ENABLE_CRYPTODISK which should be set on for it work. Then GRUB will ask for your password to access the boot partition to load the config file and stuff.
The only drawback is that you have type the password two times, once in grub and second while the initramfs is mounted.
Tested full disk encryption on archlinux, works perfectly.
