38 Chapter 2 Creating Boot and Install Images

About Packages

If you plan to add application software or other files to an image at creation time

(instead of installing the applications or files on the image source volume before you

create the image), you need to group the applications or files into a special file called a

package.

A package is a collection of compressed files and related information used to install

software onto a computer. The contents of a package are contained within a single file,

which has the extension “.pkg.” The following table lists the components of a package.

Creating Packages

To add applications or other files to an image (instead of installing them first on the

image source volume before creating the image), use PackageMaker to create

packages containing the application or files. PackageMaker is in the Utilities folder on

the Mac OS X Server Administration Tools CD that comes with Mac OS X Server.

For more information on creating packages, open PackageMaker and choose

PackageMaker Help, PackageMaker Release Notes, or Package Format Notes from the

Help menu.

After creating the packages, add them to your boot or install image using System

Image Utility. See “Creating an Application-Only Install Image” on page 39, or “Adding

Packages to a Boot or Install Image” on page 39.
