+# flake-parts TODO

+- Move logic for generating system/home configs to module (most important,
+  reason i wanted to use flake-parts)
+	- Move common default args from the awful wrapper function to dedicated options:
+		- default module imports
+		- "common" module
+			- currently defines stateVersion, nixpkgs.config.allowUnfree, a few others
+		- make default module path configurable, but still default to
+		  `./hosts/${hostname}/configuration.nix`
+		- make "entrypoint" (`./system`, `./home/standalone.nix`, etc) configurable
+		- make nixfiles home manager initialization a configurable option
+		- specialArgs (i want to deprecate this but one thing at a time)
+		- define system "types" and generate all of them internally using lazy
+		  eval. export a specific one to the flake outputs.
+			- generate as something like `nixfiles.hosts.<name>.outputs`
+			- `flake.nixosConfigurations.<name>` is set from `nixfiles.hosts.<name>.output`
+			- default chosen by option like `nixfiles.hosts.<name>.type`
+			- types:
+				- normal
+				- WSL
+				- ISO image
+	- define deploy-rs outputs in same section as hosts
+	- make common, central interface for configuring overlays to be consumed by
+	  various parts of flake, move hard-coded overlays out of common module
+		- literally just a list, maybe process it using lib.composeManyExtensions
+- some top-level config is okay (e.g., defining hosts using nixfiles options).
+  hide away all of the internal logic into imported modules.
+- move random functions into nixfiles lib
+- move top-level universal configs (username, mobileTimeZone) into option
+  (honestly, this alone makes flake-parts worth it)
