My previous install(s) have usually been a (~)250Mb boot partition for Syslinux, and then the partition for LVM with N mountpoints. This explains how to enable a machine with an encrypted disk to decrypt it securely on unattended boot. The image was generated from a Ubuntu 18. This is the point where - if you select ‘Yes’ to install GRUB to a hard disk - the installer stumbles over the encrypted boot directory and the install will fail. So that's one easy way to do it. Whilst possibly the most secure option, it is also the most awkward for the user as they must remember to always pull the drive when leaving the laptop unattended, including safely unmounting the /boot partition, if not already unmounted. sdX is of course your LUKS device. Near the end of the install process is the GRUB boot loader setup. This could be exploited by an attacker if you leave your workstation unattended and unlocked while still being logged in. div> With the following command the created key file is added as a key to the luks encrypted volume.
