Here's the bare minimum to get daemontools running under systemd
cat <<CNF > /usr/lib/systemd/system/daemontools.service [Unit] Description=DJB daemontools After=network.target [Service] ExecStart=/var/daemontools/command/svscanboot Restart=always [Install] WantedBy=multi-user.target CNF systemctl enable daemontools systemctl start daemontools
Note that the default daemontools install would put the executable in /command/svscanboot.
