Allocation of Shadow Files for Mac OS X NetBoot Clients
When a client computer starts up from a Mac OS X boot image, it creates its shadow
files on a server NetBootClientsn share point or, if no share point is available, on a drive
local to the client. For information about changing this behavior, see “Changing How
Mac OS X NetBoot Clients Allocate Shadow Files” on page 35.
NetBoot Image Folder
When you create a Mac OS X NetBoot image with System Image Utility, it automatically
creates a NetBoot image folder whose name ends with “.nbi” and stores in it the
NetBoot image and other files (see table below) required to start up a client computer
over the network. System Image Utility stores the folder whose name ends with “.nbi”
on the NetBoot server in /Library/NetBoot/NetBootSPn/image.nbi (where n is the
volume number and image is the name of the image) Files for PowerPC-based
Macintosh computers are stored at the root level of the folder, those for Intel-based
Macintosh computers are stored in the i386 directory.
You use System Image Utility to set up NetBoot image folders. The utility lets you:
 Name the image
 Choose the image type (NetBoot or Network Install)
 Provide an image ID
 Choose the default language
 Choose the computer models the image will support
 Create unique sharing names
 Specify a default user name and password
 Enable automatic installation for install images
 Add additional package or preinstalled applications
See “Creating a Mac OS X Boot Image” on page 29.
The name of a NetBoot image folder has the suffix “.nbi.”
