I=E2=80=99m interested in your feedback then. To me, there are already several ways to do that, notably: 1. guix environment (but it=E2=80=99s slower) 2. sh . /my/profile/etc/profile.sh exit 3. sh eval `guix package -p /my/profile --search-paths` exit Options #2 and #3 are more verbose, and less obvious to someone not familiar with the shell. Still, such commands are targeting shell users, which makes me wonder how far we should go. It=E2=80=99s an honest question: I=E2=80=99m torn be= tween the will to provide a simple CLI, and the need to avoid proliferation of commands all more or less equivalent. Thoughts? Ludo=E2=80=99.
