please adopt nixos/infra gc settings on the ofborg macs, so monitoring shuts up 🙂

    gc = {
      automatic = true;
      interval = {
        # hourly at the 15th minute
        Minute = 15;
      };
      # ensure up to 125G free space every hour
      options = "--max-freed $(df -k /nix/store | awk 'NR==2 {available=$4; required=125*1024*1024; to_free=required-available; printf \"%.0d\", to_free*1024}')";
    };
