# This script uses the KIWI 'editbootconfig' hook to modify the Live layout
# and ISO generation.
#
# Note that the 'editbootconfig' hook runs before the initrd is generated -
# this is too early for our purposes. So we have to do some gray area
# trickery:
#
# 1. Inject our modification scripts via config-cdroot.tar.xz into the Live tree.
# 2. Inject a 'xorriso' wrapper script into /usr/local/bin to hook into the ISO
#    creation directly.
#    This script (a) adjusts the boot config, (b) runs xorriso, and (c) makes
#    it zIPL bootable on s390x.
