Home Manager Manual

nixpkgs.config

The configuration of the Nix Packages collection. (For details, see the Nixpkgs documentation.) It allows you to set package configuration options.

If null, then configuration is taken from the fallback location, for example, ~/.config/nixpkgs/config.nix.

Note, this option will not apply outside your Home Manager configuration like when installing manually through nix-env. If you want to apply it both inside and outside Home Manager you can put it in a separate file and include something like

  nixpkgs.config = import ./nixpkgs-config.nix;
  xdg.configFile."nixpkgs/config.nix".source = ./nixpkgs-config.nix;

in your Home Manager configuration.

Type: null or (nixpkgs config)

Default:

null

Example:

{
  allowBroken = true;
}

nixpkgs.overlays

List of overlays to use with the Nix Packages collection. (For details, see the Nixpkgs documentation.) It allows you to override packages globally. This is a function that takes as an argument the original Nixpkgs. The first argument should be used for finding dependencies, and the second should be used for overriding recipes.

If null, then the overlays are taken from the fallback location, for example, ~/.config/nixpkgs/overlays.

Like nixpkgs.config this option only applies within the Home Manager configuration. See nixpkgs.config for a suggested setup that works both internally and externally.

Type: null or (list of (nixpkgs overlay))

Default:

null

Example:

[
  (final: prev: {
    openssh = prev.openssh.override {
      hpnSupport = true;
      withKerberos = true;
      kerberos = final.libkrb5;
    };
  })
]
