Browsing the internet about secure boot and NixOS, I found the article of one of the creators

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...

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.
