I want to install upstart to my ubuntu server 13.10, but I am confused if I need to download the source or install package. In upstart's getting started page I think they instruct to install the source.
But here and here they seem to say that upstart is included with later distributions. I tried
initctl in the shell and I got missing command error. Does this mean I need to install it from source? I am new to ubuntu so I would appreciate if you can explain how I can install upstart.
