Huh, as a Lanaboote user I’m surprised to see this on the front page. I use this in combination with sbctl for key generation. I’m mostly using it because I wanted to set up full disk encryption with TPM2 auth.
Lanzaboote is great, I've been using it for almost a year now in a dual boot with Windows 11 for full secure boot on my desktop. It is quite stable (notably was set and forget) and the initial setup was relatively easy.
Probably integrating something like sbctl (https://github.com/Foxboron/sbctl#sbctl---secure-boot-manage...) would do the trick, it's making the whole signing and key management dance easy.
Seems to already work together with limine on NixOS too: https://search.nixos.org/options?channel=25.11&query=sbctl#s...
