https://wiki.gentoo.org/wiki/Dm-crypt_full_disk_encryption yup why would we do that? https://wiki.archlinux.org/title/dm-crypt/Encrypting_an_entire_system#Avoiding_having_to_enter_the_passphrase_twice
FAFO keyfile decryption
root # mkdir /etc/keys root # dd if=/dev/urandom of=/etc/keys/enc.key bs=1 count=4096 root # cryptsetup luksAddKey /dev/sdX3 /etc/keys/enc.key
then setup grub to load the key file, or initramfs or something? does anybody do this?
