And maybe, an entry to the >>> Cookbook could be worth. I withdraw the patch proposal since the patch set #43578 [1] fulfills the request. Now, for recompiling all the Emacs packages of one manifest.scm file with the emacs-next package (changing the Emacs VM), it is as easy as: --8<---------------cut here---------------start------------->8--- guix build -m manifest.scm --with-input=emacs-minimal=emacs-next --8<---------------cut here---------------end--------------->8--- Before closing, what do you think adding something in the manual or the cookbook will be worth? It could be useful when switching the Emacs version –– for example the last 26 to 27. [1] <http://issues.guix.gnu.org/issue/43578> All the best, simon
