Running Programs at Boot Time

The file /etc/rc.d/rc.local script is run by the init command at boot time, or when changing runlevels, after all other initialization is complete. You can use this file to add additional commands necessary for your environment. For instance, you can start additional daemons or initialize a printer.

In addition, if you require serial ports setup at boot time, you can create and edit /etc/rc.serial. This script runs setserial commands to configure the system's serial ports. See the setserial man page for more information.
