- Also make `lib` an `internal` option
- Unify let blocks and move them under `imports`
(makes it clear where `config.lib` comes from)
- Fix a minor typo
Flatten down directory structure:
- From: `./hosts/${configuration-type}/${system}/{configuration,deploy}.nix`
- To: `./hosts/${configuration-type}/{meta,configuration}.nix`
Keep `system` and `deploy-rs` config in `meta.nix`
Update `flake.lock`
