zcfan for OpenRC
OpenRC init file for zcfan.
OpenRC init file I once wrote for zcfan - zero-configuration fan control daemon for ThinkPads. Zcfan is really simple, with 3 default fanspeeds / temperatures, optionally configurable with a file. If you want a more fine-grained control, you could try thinkfan. I also wrote an openrc init script for thinkfan.
I added supervise-daemon support for easy managing the service. The code of zcfan-openrc can be found on my GitHub, or you can install it from the AUR.
