 - Actually tolerate the `--yes` param to `resin device init`
 - Allows passing `--drive` to `resin device init`
 - List detected drives with `resin os available-drives`
+- Add the `resin os build-config` method to pass the interactive config step once
+and reuse the built file for consequent `resin os configure` calls (added the new `--config` param to it),
+and for `resin device init` (same `--config` param)
