NullBite's NixOS Config

This is my personal NixOS config. Right now, it's just a basic flake which imports a (mostly) normal stock NixOS configuration. The plan is to have three separate levels of organization:

• Fragments: Configure one specific service/app/setting/etc., which has the potential to be used on more than one machine.
  • Settings that will only ever work on one machine (e.g., settings which include disk UUIDs, PCIe bus IDs, etc) should be placed in a host fragment instead.
• Roles: Define a "purpose" and import relevant fragments.
  • Roles aren't mutually exclusive; one system could pull in roles for, e.g., desktop environment, gaming, and server
  • This is inspired by the concept of roles in Ansible
• Hosts: Configuration for individual hosts (obviously).
  • Each host shall have a folder containing a configuration.nix and a hardware-configuration.nix, and possibly a few host-specific fragments.
  • Custom configuration MUST NOT be placed in hardware-configuration.nix for the same reason one should not directly edit hardware-configuration.nix on a stock NixOS system. Most systems, however, generally will have some options exclusive to them, and these should be placed in the host's configuration.nix or a host fragment.

At first I am going to migrate configuration into roles, and then as the configuration evolves, I will start to create fragments.

flake.nix schema

flake.nix shall contain a "default" configuration for each host (using the built-in selection of nixos-rebuild), as well as alternative config presets for the host, if applicable.
