4 Click Images, select the image, and click Edit.

5 Click Contents and choose the updated source volume from the Image Source pop-up

menu.

6 Click Save.

7 Reenable the image using Server Admin.

Choosing the Protocol Used to Deliver an Image

You can use either NFS or HTTP to send images from the server to a client. You can

choose the protocol when you create the image using System Image Utility or later

when the image is listed in Server Admin.

To choose the protocol when you create the image, choose either NFS or HTTP in the

General pane in System Image Utility.

To choose the protocol for an existing image, choose the NetBoot service in Server

Admin, click Settings, and choose a protocol from the pop-up list next to the image in

the Images pane.

From the Command Line

You can also change the delivery protocol by modifying the image’s

NBImageInfo.plist file using Terminal. For more information, see the system image

chapter of the command-line administration guide.

Compressing Images to Save Disk Space

You can create compressed images by setting a preference in System Image Utility.

To create compressed images:

1 Open System Image Utility.

2 Choose System Image Utility > Preferences and select “Compress image when creating

or editing.”

Be sure the volume on which you’re creating the image has enough free space for both

the uncompressed image and the compressed image.

From the Command Line

You can also compress images using the hdiutil command in Terminal. For more

information, see the system image chapter of the command-line administration guide.
