With systemd if you want to override a system unit make a copy into the /etc/systemd/system folder, and make your changes there. So `cp /lib/systemd/system/snmpd.service /etc/systemd/system/snmpd.service` and make your adjustments to the copy. Systemd will prefer a unit from the /etc folder of a unit from the /lib/systemd.
