/etc/rc reads /etc/rc.conf which then reads /etc.rc.conf.local. After
finishing the default stuff, /etc/rc runs /etc/rc.local. Because rc runs
rc.local, rc.local inherits the same values in rc.conf and rc.conf.local.
That's how mysql=YES gets to rc.local.

The echo just prints " mysqld" to the console during bootup. Next time
you boot, look for something like "starting local services: mysql." The
echo -n is what puts the string "mysql" there. The echo and the
mysql.server start are separated by a ';' which means they are two
independent commands.
