The inittab configuration file defines several entries with a common format: id: runlevels: action: process.

Upstart provides a set of example jobs that are compatible with the typical init configuration runlevels.

Here you see that the audit and autofs services have Knn entries in all runlevels and Snn entries for both in runlevels 3 and 5.

It is important to understand that an individual service may only start in particular runlevels.

Process, at the various runlevels this involves, and how to customize your system or switch between runlevels while your system is running.

Runlevels lists the runlevels for which the specified action should be taken.

Runlevels are designated by number or letter.

Runlevels are a feature that many Linux users never have cause to learn about.
