There should be an easy method to add extra kernel config in your configuration.nix file.

Soooo... It seems that the kernels are built without taking into consideration system.requiredKernelConfig. If I have a package which requires a certain non-standard kernel feature to be enabled, or want to disable unnecessary features for size/performance/security in my configuration.nix, I should be able to do it in a nice way.

(triage) has this been added?

Not sure where to find the nixpkgs doc but I wrote some doc on how to pass extra args, excerpt from my overlay:

  my_lenovo_kernel = prev.linux_latest.override({
    extraConfig = bpfConfig + net9pConfig + mininetConfig + ''
      OPENVSWITCH m
    '' ;
  });

I don't think you can disable default args without writing your own full config but that should change with #41393

Doesn't #42838 solve this?

Ops' opening:

is adressed by #55755 which is just a PoC. Hoping to get some feedback before cleaning up (now that the "koi" release is out, we may get more).

Thank you for your contributions.

This has been automatically marked as stale because it has had no activity for 180 days.

If this is still important to you, we ask that you leave a comment below. Your comment can be as simple as "still important to me". This lets people see that at least one person still cares about this. Someone will have to do this at most twice a year if there is no other activity.

Here are suggestions that might help resolve this more quickly:

1. Search for maintainers and people that previously touched the related code and @ mention them in a comment.
2. Ask on the NixOS Discourse.
3. Ask on the #nixos channel on irc.freenode.net.
