mkForce, mkDefault etc, stripped from modules ?

[theotheroracle]

i'm trying to set something as mkDefault in a module, and then mkForce the same option in the system config, but the error message prints out no mkDefault, and simply says the option was defined twice, is some stripping being done or am i just using mkForce wrong ?

for reference, the option i was trying to set was boot.supportedFilesystems = mkDefault [ "bcachefs" ];

[theotheroracle]

i was able to use mkForce normally to overide a default package option, which indicates to me that i'm either somehow using it wrong in the above example, or that perhaps there's just some issue with it from module to system config, but i'm not sure so i'll leave this open for now

can you link your config?

i would suggest creating an option with a default

{
  lib,
  config,
  namespace,
  ...
}:
let
  cfg = config.${namespace}.boot;
in {
  options.${namespace}.boot.supportedFilesystems = lib.mkOption {
    type = types.listOf types.str;
    default = [ "bcachefs" ];
  };

  boot.supportedFilesystems = cfg.supportedFilesystems;
  boot.loader.systemd-boot.enable = true;
  boot.consoleLogLevel = 3;
  boot.kernelParams = [ "quiet" ];
  boot.loader.timeout = 1;
  boot.loader.systemd-boot.configurationLimit = 5;
  boot.initrd.systemd.enable = true;
  boot.plymouth.enable = true;
  boot.loader.efi.canTouchEfiVariables = true;
}

and then setting it in your system config like this

{ lib, namespace, ... }:
{
  ${namespace}.boot.supportedFilesystems = ["ext4"];
}

[theotheroracle]

{
  lib,
  config,
  namespace,
  ...
}:
let
  cfg = config.${namespace}.boot;
in {
  options.${namespace}.boot.supportedFilesystems = lib.mkOption {
    type = lib.types.listOf lib.types.str;
    default = [ "bcachefs" ];
  };
  boot.supportedFilesystems = cfg.supportedFilesystems;
}

error: Module `:anon-1718:anon-1' has an unsupported attribute `boot'. This is caused by introducing a top-level `config' or `options' attribute. Add configuration attributes immediately on the top level instead, or move all of them (namely: boot) into the explicit `config' attribute.

ah, it should be within config

i get the same error, not sure if i did something wrong or not

{
  lib,
  config,
  namespace,
  ...
}:
let
  cfg = config.${namespace}.boot;
in {
  options.${namespace}.boot.supportedFilesystems = lib.mkOption {

  };
  config = {
  boot.supportedFilesystems = cfg.supportedFilesystems;
  };
}

nvm i figured it out; i had extra config not in the "config" option, nix is weird
