Leap and Tumbleweed TLP scheme?

All, Devs, Was surprised yesterday to find that TLP was happily running on my laptop (with tlp frequency-info) while the service was not enabled. I stumbled upon it after pulling power to my laptop and happening to see the log messages telling me I need to enable it to have it available on boot and my needing to mask systemd-rfkill.service and systemd-rfkill.socket. I'm not complaining, it's a good command line tool for power management, but didn't know how Leap was starting it since the service wasn't enabled. Anybody have the Cliff's Notes version of how this works? (I happily enable it and masked rfkill) -- David C. Rankin, J.D.,P.E.
