I've been working with CentOS 6/7 based Openstack but have some Ubuntu. FWIW, I prefer the 16.x Ubuntu with SystemD to Upstart. I've found it easier to learn with CentOS man pages than Ubuntu.
I end up using service and chkconfig to start/stop and enable/disable. I've found initctl for Upstart vs systemctl for systemd.
