RC(8)

NAME
rc - command script for boot

SYNOPSIS
rc
rc.local

DESCRIPTION
Prior to Mac OS X 10.5, the rc script was used to bootstrap the OS. As of Leopard, the system is self-bootstrapped via launchd(8) which uses the launchctl(1) bootstrap subcommand to read in launchd jobs from the standard locations. For compatibility reasons, the rc.local script still continues to work.

The startup file rc.local reside in /etc.
