Abstract
Startup items are directory bundles consisting of at least two parts, an executable file and a property list file (StartupParameters.plist). The property list file describes the startup item. Each item provides at least one named service, and may specify any dependencies on services provided by other items. SystemStarter will start items in an order honoring the listed dependencies.
Note that some aspects of SystemStarter such as partial-startup and inter-process communication are not available in Darwin 5.4 or earlier.
Table of Contents
Startup item bundles may be placed in a StartupItems directory in each of the primary file domains (as defined in NSSystemDirectories.h). SystemStarter searches for bundles in the order of /Library/StartupItems, /Network/Library/StartupItems, and /System/Library/StartupItems. The order objects are discovered does not affect the order they are executed, except in the case of conflicting Provides attributes; in this case, the first item discovered will run and subsequent conflicting items will not. (The Provides attribute is described in the Provides attribute section.)
This directory contains startup items available over the network.
Since the Network mounts are not yet established at the beginning of system startup, the StartupItems directory in /Network/Library is not searched. (A future version of SystemStarter may search this directory for items once it becomes available.)
