NixOS configs for all my systems

Primary LanguageNix

NixOs Configuration files

To apply a configuration for a particular host, e.g meshify:

sudo nixos-rebuild switch --flake .#meshify

Replace meshify with the desired host, found in hosts.

Using modules

If you want to use for example the monero.nix module in your NixOs base system, then copy modules/monero.nix into /etc/nixos/modules/monero.nix (make sure to create the modules directory in /etc/nixos). Then modify your /etc/nixos/configuration.nix file to include the module as such:

imports = [
  # Include the results of the hardware scan.
  ./hardware-configuration.nix
  ./../../modules/monero.nix
];

Now rebuild as such:

sudo nixos-rebuild switch

Updating

See the metadata and the current flake inputs:

nix flake metadata .

There one can see the Inputs.

To update the flake input nixpkgs:

nix flake lock --update-input nixpkgs

Then update the system, eg for the meshify host configuration:

sudo nixos-rebuild switch --flake .#meshify --upgrade-all

Cleaning system store manually

nix-store --gc

Tips:

When getting something like this:

  error: cached failure of attribute 'nixosConfigurations.poweredge.config.system.build.toplevel'

Then you can disable the eval-cache temporarily by running with --option eval-cache false.
