It's emitted by "ifup" and by Network Manager, both via
the /etc/network/if-up.d/upstart script.

Before, after, during, etc.  There is no fixed relationship between
these two things, except that /etc/rcS.d (and thus /etc/rc2.d) will not
be run until the "lo" device is up.

It's emitted by the /sbin/telinit tool.

Yes, or renaming to .conf-disabled is a common pattern.
