    I use sbupdate [0] to build the unified kernel image and to sign it with my keys. It's run by a hook in the arch's package manager whenever the kernel, the initrd or the firmware images change. I saw the other day that systemd recently got an utility to do this, but I've never looked into that. sbupdate has been working fine for me for several years now.

    It doesn't store a new key in the uefi, it signs the new image with the key that uefi already knows about.

    See [1] for the whole setup and [2] for the signing part specifically.

    Here is where different systems will fork. On Arch there is a pacakge sbupdate where it automatically generate unified kernel images using pacman hooks and I use systemd-boot (which must be signed by your keys) to load it.

    I really think it's easy enough. You create your keys, put them into /etc/efi-keys, enroll them into your UEFI by whatever method you prefer, install sbupdate-git and you're done... You need to run sbupdate manually once after install, everything else works automatically through hooks.
  • I've moved to a new laptop with 3 NVMe drives, and I want full encryption and Secure Boot.

    Ah, sbupdate does that very well; it embeds the kernel image, initramfs and the UEFI boot image into a unified signed image. I presume this signed image should then be further encrypted?

    For the last part, check out https://github.com/andreyv/sbupdate . Linked also from arch wiki, so not some completely random solution. Its for creating unified kernel images, including the initramfs, microcode and so on. This package is then signed for secureboot, and can be loaded using EFISTUB for example. This prevents attacks against initramfs or some other things on /boot, if unencrypted. I haven't come around to test it myself, but I think its a neat solution, and with proper secure boot (and password protected firmware), a reasonable protection against evil maid attacks.

    I am using secure boot with custom keys, a fully encrypted root btrfs partition with /boot on it, with swap also encrypted with hibernation support. The only non-encrypted partition is the EFI partition with boot images signed with https://github.com/andreyv/sbupdate (look up "direct booting").
