I have .conf a file in /etc/init/ with this code at the bottom:

start on (started network-interface
          or started network-manager
          or started networking)

stop on (stopping network-interface
         or stopping network-manager
         or stopping networking)

I understand this means that it is launched whenever the system boots. Anyway, is it possible to have a more accurate information about each one of these events? man initctl does not provide a comprehensive list of them and googling is not very successful so far.

network-interface, network-manager and networking are other Upstart jobs and are defined in /etc/init/network-interface.conf, /etc/init/network-manager.conf and /etc/init/networking.conf.

Have a look at Upstart Intro, Cookbook and Best Practises if you want to learn more about Upstart.

Quite interesting, thanks @Florian. In my case I cannot find these files in /etc/init/ neither in all /etc/. Anyway, I get the idea that it is whenever the network is available. – fedorqui Apr 23 '13 at 12:20
Which version of Ubuntu are you using? /etc/init/network-manager.conf is in package network-manager, the other two in ifupdown since Ubuntu 10.04. network-interface brings an network interface up or down, network-manager starts or stops NetworkManager, networking brings the network devices in /etc/network/interfaces marked as ´auto` up or down. – Florian Diesch Apr 23 '13 at 12:35
I am using an Amazon server, so I cannot know exactly the release of it (supposing it is Ubuntu). Anyway, the main purpose of my question is solved, so thank you very much. – fedorqui Apr 23 '13 at 13:43
