Chapter 2 Creating Boot and Install Images 35

Changing How Mac OS X NetBoot Clients Allocate Shadow Files

By default, a Mac OS X NetBoot client places its shadow files in a NetBootClientsn share

point on the server. If no such share point is available, the client tries to store its

shadow files on a local hard disk.

For Mac OS X version 10.3 and later images set for diskless booting, you can change

this behavior by using a text editor to specify a value for the NETBOOT_SHADOW variable in

the image’s /etc/hostconfig file. These values are allowed:

Note: This value is set in the /etc/hostconfig file in the image .dmg file, not in the

server’s hostconfig file.

Creating Mac OS X Install Images

The following sections show how to create images you can use to install software on

client computers over the network.

Creating an OS Install Image

To create an image that will install Mac OS X software on a client computer, use System

Image Utility. You can find this application in the folder /Applications/Server/.

To create an OS install image:

1 Log in to the server as an administrative user.

2 Open System Image Utility and click New Install.

3 In the General pane, type a name for the image you’re creating.

4 Type an Image Index number.

Choose a number in the range 1–4095 for an image that will be available on a single

server, or 4096–65535 for an image that you plan to make available on multiple servers

but want to list only once in the client computer Startup Disk preferences.

Value of NETBOOT_SHADOW Client shadow file behavior

-NETWORK- (Default) Try to use a server NetBootClientsn share point for storing

shadow files. If no server share point is available, use a local drive.

-NETWORK_ONLY- Try to use a server NetBootClientsn share point for storing shadow

files. If no server share point is available, don’t boot.

-LOCAL- Try to use a local drive for storing shadow files. If no local drive is

available, use a server NetBootClientsn share point.

-LOCAL_ONLY- Try to use a local drive for storing shadow files. If no local drive is

available, don’t boot.
