In some cases, such as for guix-packages- base.drv and guix-packages.drv, this happens several dozen times before the build is actually complete. This is a bug. Progress bars should *never* go backward. It is actually better to have no progress bar at all than to have one that gives a misleading sense of how close the operation is to completion. zw
