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.
