Jenkins systemd service file
This is a small snippet to run Jenkins via systemd service unit and not via the included init.d file (which systemd need to auto-generate a unit for it).
Copy the file into `/etc/systemd/system/jenkins.service` and run `systemctl daemon-reload`
# /etc/systemd/system/jenkins.service
