# to install with full disk encryption and more than 1 partition, you need to either 
* enter your password for each encrypted partition (also your disk layout is transparent)
* install a helper to enter a single password multiple times
* put all the partitions into LVM and decrypt once (at the cost of more abstraction layers)

with EFI + GRUB + LVM on a big LUKS on /dev/sda, these are the steps:
1. partition with a small (~300MB ESP partition for EFI) as /dev/sda1, and a large LUKS partition as /dev/sda2
2. encrypt /dev/sda2
  `cryptsetup -v --type luks --iter-time 5000 --verify-passphrase luksFormat /dev/sda2`
  --iter-time increases iterations of pbkdf2, to increase security at the cost of time
