I was already using package-input-rewriting (well, the /spec version of it) but supplemented it with the keyword argument substitution because I thought it only worked on the inputs / native-inputs / propagated-inputs fields. But you are right, just the input-rewriting works!

Recursive substitute-keyword-arguments / setting default on build system
Hello, I use a slightly customized emacs package, and want to use it as the package that is used in emacs-build-system for the emacs plugins I'm using. The default emacs gets garbage collected and takes quite a while to reinstall, I would like to avoid that. Also, it seems cleaner to build the plugins with the exact version that they will be used with. Here's what I have: (define emacs-package ((const ((options->transformation '((with-configure-flag . "emacs=--program-transform-name='s/^ctags$/ctags.emacs/'"))) emacs (define (set-build-system-emacs plugin-package) (package (inherit plugin-package) (arguments (substitute-keyword-arguments (package-arguments plugin-package) ((#:emacs emacs) `,emacs-package) (map set-build-system-emacs package-list) >From what I can tell this does work for the packages in package-list, but not >for any inputs to those packages. That makes total sense to me, but I don't >know how to solve it. Any pointers? Or is it possible to set the default package for a build system, removing the need for this mapping altogether? Nils
