Every published flake was three inputs, two follows, an import and a nested option block, of which one line was about the project. It is now the call and the settings: outputs = inputs: inputs.project ./. { name = "oxidized-sed"; ... }; The nixpkgs revision goes with it. It was written into all thirty-eight files to keep them building against one nixpkgs; the callable flake closes over its own inputs, so they share nixpkgs by construction and each lock has a single direct input.
