However, note that, $ guix time-machine --commit=3Dba60bbd4 \ -- install emacs emacs-xwidgets -p /tmp/foo $ guix time-machine --commit=3Dba60bbd4 \ -- install emacs-xwidgets emacs -p /tmp/bar readlink -f /tmp/{foo,bar}/bin/emacs /gnu/store/xy38cgnr21j2jsb5mnn9cf91d6q67as2-emacs-xwidgets-27.1/bin= /emacs-27.1 /gnu/store/1zwmmfy1d213mrqixl36ckbzghkpqdmf-emacs-27.1/bin/emacs which is a bug. AFAIU. Same with =E2=80=9Cguix package -i=E2=80=9D. > I also suggest to raise an error when conflict detected during building > profile to force user to resolve it. It should be already the case. :-) All the best, simon
