Hello all, currently I have a working LUKS encrypted /boot ( and / for that matter ). For my other LUKS encrypted filesystems I am switching to using a keyfile on an external drive (instead of using a password). However each time at boot GRUB asks me for the password (which is an excellent fallback in this scenario). But I am wondering, is it possible to use a keyfile on a USB drive, instead of using a password, to unlock GRUB at boot? Thank you in advance.
Cheers, Chris
