# Uses adjacent Ubuntu Autoinstaller from installers/
#
# 'packer' command must be run from the same directory as this file so the autoinstaller files provided are auto-served via HTTP:
#
# - Ubuntu AutoInstaller - autoinstall-user-data and meta-data files

# WARNING: XXX: Do not build on ARM M1/M2 Macs using VirtualBox 7.0 - as of 2023 VirtualBox 7.0 Beta is extremely buggy, slow,
#               results in "Aborted" VMs and so slow it even misses bootloader keystrokes - it is unworkable on ARM as of this date
