Indeed, good catch. Commit 6e1a7d1 fixes it. > So build commands will just ignore such options as "--no-grub" or > "--no-substitutes" if a user didn't tweak GUIX_BUILD_OPTIONS. The problem was in fact specific to the option handler for --no-grub; the one for --no-substitutes (and all the others I checked) always conses, so there’s no problem. Thanks, Ludo’.
