Administration

This chapter describes how to start up client computers using

an operating system stored on a server and how to install

software on client computers over the network.

The NetBoot and Network Install features of Mac OS X Server offer you alternatives for

managing the operating system and application software your Macintosh clients (or

even other servers) need to start up and do their work. Instead of going from computer

to computer to install operating system and application software from CDs, you can

prepare an install image that is automatically installed on each computer when it starts

up. Or, you can choose not to install software on the clients at all but, instead, have

them start up (or “boot”) directly from an image stored on the server. In some cases,

clients don’t even need their own disk drives.

Using NetBoot and Network Install, you can have your client computers start up from a

standardized Mac OS configuration suited to their specific tasks. Because the client

computers start up from the same image, you can quickly update the operating system

for the entire group by updating a single boot image.

A boot image is a file that looks and acts like a mountable disk or volume. NetBoot boot

images contain the system software needed to act as a startup disk for client

computers via the network. An install image is a special boot image that boots the

client long enough to install software from the image, after which the client can start

up from its own hard drive. Both boot images and install images are special kinds of

disk images. Disk images are files that behave just like disk volumes.

You can set up multiple boot or install images to suit the needs of different groups

of clients or to provide several copies of the same image to distribute the client

startup load.

You can use NetBoot in conjunction with Mac OS X client management services

to provide a personalized work environment for each client computer user.

For information about client management services, see the user management guide.
