The file /etc/rc.d/rc.local script is run by
init at boot time, after all other initialization is
complete, and whenever you change runlevels. You can add additional
initialization commands here. For instance, you may want to start up
additional daemons or initialize a printer.
In addition, if you require serial port setup,
you can create and edit /etc/rc.serial, and it will be
executed automatically at boot time. This script can run a number of
setserial commands to specially configure the
system's serial ports. See the setserial man page for
more information.
