All systemd 'objects' are units and have the general unit file stanza and syntax in them: [Unit] Description=blurb goes here Documentation=man page name here Requires=dependencies generated from here After=network.target And so on - see man systemd.unit for full details. After that section depending on the type of unit you are working with (timer, service, mount, etc) there will be an appropriate section with entries specific to that: [Service] Type=oneshot RemainAfterExit=true ExecStart=/usr/sbin/ifup dummy0 ExecStart=/usr/sbin/ip link set multicast on dummy0 ExecStop=/usr/sbin/ifdown dummy0 Does that make more sense?
