By default, an OS X Yosemite NetBoot client places its shadow files in a NetBootClientsn share point on the server, where n is the share point number. If no such share point is available, the client tries to store its shadow files on a local hard disk.
For OS X v10.3 or 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.
This value is set in the /etc/hostconfig file in the image .dmg file, not in the server hostconfig file.
These values are permitted:
Value of NETBOOT_SHADOW | Client shadow file behavior |
|---|---|
-NETWORK- | (Default) Try to use a server NetBootClients n share point for storing shadow files. If no server share point is available, use a local drive. |
-NETWORK_ONLY- | Try to use a server NetBootClients n 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 NetBootClients n share point. |
-LOCAL_ONLY- | Try to use a local drive for storing shadow files. If no local drive is available, don’t boot. |
