If you customize them, together with a custom inittab, then you can have your system start just your application, but still do certain actions upon startup and shutdown. This is (for example) explained in "Chapter 6. System Initialization" of the book "Embedded Linux Primer. A Practical Real-World Approach" (Christopher Hallinan ; publisher: Prentice Hall).
