As said, it's triggered via udev. /{etc,lib}/udev/rules.d/10-console.rules
runs a command that checks out /dev/console - if it responds to the
proper serial ioctl, then it's determined to be a serial console. The
event is then emitted, and /etc/event.d/serial is triggered on that
event.

It only triggers if the serial console is the primary console. This is
in line with the automatic /etc/inittab writing that was there in
prior releases.
