It installs a SysV init script which SystemD generates a service file from it, but fahclient runs as the fahclient user but AFAICT SystemD doesn't know that, which I've read can cause problems with accessing the GPU.

So I went ahead and wrote a SystemD service file for fahclient, but no luck. I've also added fahclient to the video group, nope...

I've installed the packages I think I need from AMD (which are really EL 8 packages) but they all install into /opt so my current theory is that FAH isn't finding the libraries... 

Current OpenCL error is:

OpenCL: Not Detected: clGetDeviceIDs() returned -1

Anyone successfully got this working?
