Create a service, as one in the examples linked above... enable and start the service with systemctl...any feedback about your inadyn issue?
No, I didn't get time to pursue the inadyn thing. If you have any luck, do please ping!
I am sorry but I'm a noob with these things. Where do I create the service, where do I place it? And do I put the command "systemstl start transmission.service" in autostart.sh?
