Some checks failed
Check / eval (push) Has been cancelled
Weekly nomarchy-gen-prune deletes only generations that are both older than 14 days and beyond the three most recent past gens (current always kept), for system and Home Manager profiles. Stock nix.gc no longer uses --delete-older-than. checks.gen-prune covers selection self-test and unit wiring; doctor points at the new tool when disk is tight.
