# This script is necessary for initial interaction with the virtual
# machine, as the other route is to dissect the ISO image, stitch in
# a script, and suture it shut (that is the method used with the TBox
# hardware boot image).
#
# Notes:
# - Only call this script from the Makefile
# - Don't attach the ISO drive as readonly, because pfSense panics
# - All bridge interfaces must have STP enabled, otherwise qemu freezes
