I'm trying to get a command to run on boot and wrote an upstart .conf file and put it into /etc/init. It's a brand new EC2 instance and theres was already bunch of .conf files there. My file wasn't working and I found out that upstart is NOT installed.
Why are there files in /etc/init if there's no upstart? Also, what's the preferred way to run a command on boot in ubuntu 16.04?
