AFAICS, it’s working as expected:
--8<---------------cut here---------------start------------->8---
$ guix gc --references $(guix build emacs-magit --with-input=emacs-no-x=emacs-next -d --no-grafts) |grep emacs-next
/gnu/store/8ffjg2961x30171i24pl7j9wafcbli2b-emacs-next-28.0.50.1-0.2ea3466.drv
$ guix gc --references $(guix build emacs-magit --with-input=emacs-no-x=emacs-next -d --no-grafts) |grep emacs-no-x
--8<---------------cut here---------------end--------------->8---
Now, there dependencies in the graph that depend on ‘emacs-minimal’
instead of ‘emacs-no-x’, so you’d probably also need to replace those.
HTH,
Ludo’.
