I'm on Yeah, it has to do with the new build handler and the lack of “parallelism” when building the system derivation: https://lists.gnu.org/archive/html/guix-devel/2020-03/msg00337.html I think we’ll improve it over time by introducing more parallelism there. Fundamentally though, we have to understand that ‘--dry-run’ can only print the first derivation plans, not those that are dynamically built as a function of build results. Thanks, Ludo’.
