Not exactly, to include Guix inside the installer image, it somehow needs to refer to itself. The way it used to be done was by using the `guix` package, which necessarily is older than the current commit. However, we also implemented the `current-guix` hack that basically uses a guix checkout at the current guix version as the source for the guix package. In both cases though, we shouldn't see any differences in other package's derivations… Best, -- Josselin Poiret
