I'm gonna be honest, I use NixOS, but the docs fucking suck, and a number of things are just broken in nixpkgs. For instance, I recently discovered the
structuredExtraConfigoption for patching the kernel straight up does not work. This means you cannot unset any kernel options, which means some kernel patches won't work unless you manually supply the entire kernel config.EDIT: what's even more annoying about it not working is that it fails to apply silently. In other words, your kernel tries to compile and then an hour later it fails because your config changes weren't applied.
From reading, I thought this option was for adding options, not removing them. Sure, you might be able to set options to "no", but I don't think this will override the defaults...
You're supposed to be able to use
lib.kernel.unsetto unset them. In any case, that's just one problem. The main issue is the entire option is ignored because of a typo in nixpkgs.Would you mind opening a PR to fix that typo? Would be useful for others as well!
I'm planning to, I'm waiting for the kernel to finish building rn lol
EDIT: PR got merged BTW (https://github.com/NixOS/nixpkgs/pull/431115).
lol
Thank you for your work!
I would not have liked encountering this bug in the wild.
Haha, perfect 😄
