# This allows NFS booting to work while also being able to configure
# the network interface via DHCP when not NFS booting. Otherwise, a
# NFS booted system will likely hang during DHCP configuration.
# Attempting to configure the network interface used for NFS will
# initially bring that network down. Since the root filesystem is
# accessed over this network, the system hangs.
# This script is run by ifup and will attempt to detect if a NFS root
# mount uses the interface to be configured (IFACE), and if so does
# not configure it. This should allow the same build to be disk/flash
# booted or NFS booted.
