I think it is bad for these reasons when `tests/` contains a mix of functional and integration tests - Concepts is harder to understand, the documentation makes a good unit vs functional vs integration distinction, but when the integration tests are just two subdirs within `tests/` this is not clear. - Source filtering in the `flake.nix` is more complex. We need to filter out some of the dirs from `tests/`, rather than simply pick the dirs we want and take all of them. This is a good sign the structure of what we are trying to do is not matching the structure of the files. With this change we have a clean: ```shell-session $ git show 'HEAD:tests' tree HEAD:tests functional/ installer/ nixos/ ```
