Ubuntu 16.04, webmin 1.831
The startup and shutdown page does not seem to match the wiki ( http://doxfer.webmin.com/Webmin/Bootup_and_Shutdown ), I have no "Create a new bootup and shutdown action" link, only "create a new upstart service". I can edit actions, but seem unable to create one. I have some simple commands that I need to run whenever the systems restarts, and Im trying to figure out how to do it.
Why is my webmin bootup and shutdown not shoing this option?
Is there another way to make the system run a script on startup?
