Confused about connection between an option in rc.conf and the associated action?

I think init just runs /etc/rc on bootup; I'm not sure, but that's certainly
one of the things it does.

In any case, /etc/rc then runs each of the scripts in /etc/rc.d:

	files=`rcorder ${skip} /etc/rc.d/* 2>/dev/null`

	for _rc_elem in ${files}; do
		run_rc_script ${_rc_elem} ${_boot}
	done

It seems that the scripts in /etc/rc.d then look at the various configuration
files.

For example, /etc/rc.d/sshd will only actually start sshd if the sshd_enable
option is set in /etc/rc.conf.  rc.conf doesn't do anything itself; it merely
contains options that other scripts read.
