During installation, there should be a warning showing there's a conflict, and which one is being chosen. So you get the "right" one by luck. > The best info I found on the rename vs rename issue in general: > https://unix.stackexchange.com/questions/275254/why-is-the-rename-utility-on-debian-ubuntu-different-than-the-one-on-other-distr To eliminate this conflict, I can think of 2 solutions: 1. Use 2 separate profiles where one has util-linux installed and the other has rename installed. 2. Install util-linux into the default profile, but invoke rename by "guix environment --ad-hoc rename -- rename ..." instead of "rename ..." These 2 solutions work in general as well, such as for conflicting library versions, conflicting language runtimes... I prefer the 2nd solution since maintaining 2 separate profiles just for using rename seems too "heavy weight" to me. Cheers, Alex
