@raitobezarius:matrix.orgraitobezariusthat looks like nixos actually15:42:27
@raitobezarius:matrix.orgraitobezariusi didn't see anything like this, could it be a random nixos change that happened at the same time?15:43:01

@minman:matrix.orgminmanI have question about overriding nix files.

What would be the best way to do this? https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/installer/sd-card/sd-image-aarch64.nix14:07:28

For now I have something like this:

in
{
  imports = [

  nixpkgs.config.packageOverrides = pkgs: {
      sdImage = sd-image.sdImage.override {
        populateFirmwareCommands = "overrideCommands"
     }
  }

For now I have something like this, it builds but the command is not overridden.

{
