Chapter 4 Setting Up Clients to Use NetBoot and NetInstall Images 59
Changing How 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 v10.3 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 /etc/hostconfig file.
These values are permitted:
Note: This value is set in the /etc/hostconfig file in the image .dmg file, not in the
server hostconfig file.
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.
