Chapter 2 Creating Boot and Install Images 33

Creating a Mac OS X Boot Image from an Existing System

If you already have a client computer set up to suit your users, you can use System

Image Utility to create a boot image that is based on that client’s configuration,

including its architecture.

You need to boot from a volume other than the one you’re using as the image source

(boot from an external FireWire hard disk or a second partition on the client’s hard disk,

for example). You can’t create the image on a volume over the network.

To create a boot image based on an existing system:

1 Boot the computer from a partition other than the one you’re imaging.

2 Copy System Image Utility to the client computer.

Note: To create architecture-specific images you must have Mac OS X 10.4.4 or later and

the latest version of the System Image Utility. Use Software Update to obtain the latest

version.

3 Open System Image Utility on the client and click New Boot.

4 Click Contents and choose the partition to use from the Image Source pop-up menu.

5 Enter the remaining image information in the other panes as usual, then click Create.

6 After the image has been created on the client, export it to the server.

Click Images, select the image in the list, and click Export.

From the Command Line

You can also create a boot image clone of an existing system using the hdiutil

command in Terminal. For more information, see the system image chapter of the

command-line administration guide.

Synchronizing an Image with an Updated Source Volume

If you create an image from a system volume and later update the original volume, you

can automatically apply the updates to the image without re-creating it using System

Image Utility.

Important: Be sure you synchronize the image with the correct original volume.

The updated original volume must be a local volume on the server where the image is

being edited.

To sync an image with an updated source volume:

1 Make sure that the image you want to synchronize is not in use.

2 Open System Image Utility (in /Applications/Server).

3 Choose System Image Utility > Preferences, enable “Add items and sync with source

when editing,” and close the preferences window.

Note: Due to the nature of the block copy process, you cannot add items to an image

that has been created with block copy enabled.
