Make sure cpupower starts after the list of governors is available On EeePC 1015 PED (in Live mode), cpupower.service seemed to start too early, before /sys/devices/.../scaling_available_governors was there, and failed as a result. There were no such problems on faster machines, but still. Now cpupower.service will start only when 'scaling_available_governors' file is available. cpupower.path unit handles this. If CPU frequency scaling is not supported the file will never appear and cpupower.service will not start at all, which is natural. 2015-03-17 20:53:12 +03:00			`[Unit]`
