@tom @rodrigo. Ok. Thank you to make it more clear for me. And I thought the gpm arg declared in /etc/conf.d/gpm was needed. It is not here. But others might need it. Hence the bug (feature request) not opened by me. Yes. The only needed part was the [Install] one So, configuration will be handled inside systemd custom service file ?? @rodrigo: +1 for .include but it does not work if one have to change an already defined directive. But your example is good.
