This chapter explains the 10.x system start-up and shutdown model and outlines the differences between HP-UX Releases 9.x and 10.x. All of the changes apply to both S700 and S800 computer systems. These differences will primarily affect software developers and system administrators. Software developers will construct rc files in a different manner, specifying run-level execution order and enabling control through configuration variables. System administrators will control subsystem behavior, on a per-host basis, by modifying variables that control subsystem start-up and shutdown.

These topics are covered in the following sections:

Introduction: the rationale for, and an overview of, the model.
Start-up/Shutdown Specifications: the specifications of the new model.
General Developer and User Impacts: explanation of affected areas.
