On ubuntu 14 I have a super simple file here on my
Inside, it only contains :
start on runlevel  exec /etc/myfolder/myscript
If I do the same thing on an ubuntu 16 server nothing happens - I assume this is because there are new ways to start things now. Looking at the man pages it looks reasonably complex, multiple files and commands required to set something up. So my question is, what is the simplest and shortest file I can create to ensure my script runs on startup?
