on ubuntu 16.04.4 server and downloaded the latest install-ns.sh and install-oacs.sh files.

kmw@fremont:/lib/systemd/system$ sudo nano oacs-5-9.service
kmw@fremont:/lib/systemd/system$ sudo systemctl daemon-reload
kmw@fremont:/lib/systemd/system$ sudo systemctl enable oacs-5-9.service
kmw@fremont:/lib/systemd/system$ sudo systemctl is-enable oacs-5-9.service
Unknown operation is-enable.
kmw@fremont:/lib/systemd/system$ sudo systemctl is-enabled oacs-5-9.service
