Personal NixOS configuration. Not intended for outside consumption, but I won't stop you.
Directory for each nixos configuration exposed, handling partitioning, booting, and host-specific quirks.
The modules directory contains NixOS modules that either map from one option to another (i.e. home. to home-manager.users.${settings.user.name}), expose new options (i.e. substituters) or expand upon existing modules (i.e. impermanence).
They're imported for all hosts, regardless of other setup.
Roles define larger chunks of configuration exposing enabling specific tasks or functionality. They're not necessarily universal, so they're applied on a per-host basis (see config.nix).
