And the fix is to put in a test that checks if we are trying to read the
file that we were called from:

for i in ${rc_conf_files}; do
    if [ $0 != $i ]; then
         if [ -f $i ]; then
                 . $i
         fi
    else
        echo "Error: $0 isn't allowed to re-load $i."
        echo "Error: Please do not copy /etc/defaults/rc.conf to
/etc/rc.conf"
    fi
done

When someone does copy /etc/defaults/rc.conf to /etc/rc.conf, /etc/rc.conf
will detect that it is calling another copy of it's self and not load it.
It will re-load all the other ${rc_conf_files}.
