Custom kernel builds support (?)

[daper]

Hi, when I patch the kernel by boot.kernelPatches. It rebuilds it and breaks secure-boot with an error: kernel hash does not match at boot. Not very knowledgeable here, is it something that lanzaboote has to do at build time? Or am I doing something wrong? If anyone has found in the same situation I would appreciate some help.

Might be related with #88?

lanzaboote works with custom kernels, I am surprised that you are running into this problem.
Can you minimize this as a reproducer in a NixOS test?

@RaitoBezarius I'll see if i can reproduce it in a virtualmachine... 🤔 not quite easy.

@daper If you can share your configuration, we can take a look. I regularly boot patched kernels on my Lanzaboote setup without issues.
