Upstart hasn't really done away with runlevels (yet). Right now, it is
really just emulating init. If you check /etc/event.d , you'll see that
it really just runs scripts appropriate to whatever runlevel the is. In
particular, /etc/event.d/rc-default performs the magic to determine the
default runlevel, based on kernel command-line args, presence of
an /etc/inittab file, or runlevel 2 by default. 

	Why 2 was chosen, and the old networkless runlevel 2 done away with, I
have no idea. It could have been implemented within upstart's
configuration, they just chose not to.
