Otherwise, Guix tries very hard to build portable packages [2]. Personally, I see only 2 cases to have substitutes turned off: 1) you often challenge your builds against substitutes ones and report reproducibility or performances issues, 2) you inspect all the sources for trusting them before building. If not, for what my opinion is worth, I do not understand the aim for burning such energy in this world of climate change. 1: 2: Cheers, simon
