# Requires macOS Ventura 13.4
#
# Must run 'scripts/prepare-ubuntu-22.04.sh' first to download the ISO and generate another ISO with the AutoInstaller config
#
# Must run 'python3 -m http.server -d installers' from this same directory before running 'packer'
#
# 'packer' command must be run from the same directory as this file so the ISO files are found under iso/
