Thanks for pointing to that commit. It's much better this way. :-) So, what makes 'guix package --search-paths' so slow? It doesn't have to check for conflicts because that's already done on profile creation time. All it has to do is combine the search-path data and output that.. Anyway, I worked around it by using the $PROFILE/etc/profile file and unset the environment variables before setting them, which takes less than a second. Kind regards, Roel Janssen
