+1

Being an old UNIX hacker that is familiar with traditional init behavior, I was quite
confused when my console login disappeared and my laptop booted into GDM. It took me
quite a bit of digging to finally understand the startup logic for upstart (at least
I *think* I understand it). Might be a good idea to put some sort of blurb in the
init(8) manpage that tells how events get propagated.

As I understand it, everything in the current setup (runlevel emulation) keys from
the "start on startup" phrase in rcS. Maybe a comment in rcS that all the runlevel
stuff starts there?
