-# Define: NETBOOT_SHADOW
-# Purpose:
-# To change the behavior of the system when choosing a netboot shadow
-# to use.
-# Values:
-# -NETWORK- Try to use the network for the shadow file, if
-# that fails, use the local drive
-# -NETWORK_ONLY- Only use the network, fail if not available
-# -LOCAL- Use the local drive for the shadow file, if that
-# fails, use the network
-# -LOCAL_ONLY- Only use the local drive for the shadow, fail if
-# not available
