Modular NixOS config using flakes and Home manager

This config defined custom options to modify what gets configured and how, documentation on the NixOS options can be found in OPTIONS.md

Config

The entry to the system config goes as follows:

• A nixosSystem defined under nixosConfigurations in flake.nix imports the hosts configuration.nix from hosts/
  • inputs and pkgs-unstable should be passed in specialArgs
• The configuration.nix should
  • import the hardware-configuration.nix, modules/, and optionally home-manager
  • define values for custom options (see OPTIONS.md) which determine how the system gets configured
  • set networking.hostName and system.stateVersion
  • do other extra configuration as necessary, that isn't part of defined modules
