The current implementation will only try an iPXE boot from eth0. This patch sets it to try all interfaces up to 10 attempts, then reboots and starts again. Change-Id: I9259a275f5f1f248905755ec5955ace5b67fc2bd

# This is the iPXE boot script that we embed into the iPXE binary.
|
|
#
|
|
# The default behaviour is to get DHCP and assume that DHCP includes
|
|
# the filename option. It will only try eth0. If it fails, then it
|
|
# just stops.
|
|
#
|
|
# This script makes it attempt to boot from eth0. If that fails, it
|
|
# will try the next interface. This will retry 10 times before
|
|
# rebooting.
