I pushed a variant of this patch: 053839d hydra: services: Leave “guix-binary.tar.xz” GC roots. e40d961 hydra: services: Preserve Cuirass .drv GC roots. b8fc66c hydra: cuirass: Fix build product regexps. I didn’t dare remove “--gc-keep-derivations”. I reconfigured berlin just now from this commit and restarted mcron (I didn’t restart guix-daemon to avoid downtime; we should do that when the queue is close to empty). We’ll have to monitor disk usage to make sure it’s not negatively affected. Ludo’.
