To be fair, I wasn't not thinking about Go and Rust, which at least on the surface appear to have similar propagation semantics. I do however not know whether all currently propagated inputs from those two could be reclassified as linked-inputs. FWIW I don't think (most) Emacs, Python or Guile packages work that way, but I do know of at least one that would profit from having linked-inputs. > What do you think of "build-propagated-inputs"? We don't call things build-inputs here in Guix land, that's a no-no :P > (A quick search of the ML turned up one previous discussion [0]; does > anyone know of others?) > > [0] > https://lists.gnu.org/archive/html/guix-devel/2017-02/msg00362.html W.r.t. native-inputs, I think native-inputs should propagate propagated-inputs, but not linked-inputs. Makes sense, doesn't it?
