## Ubuntu Example
#
# Demonstrates:
#
# - Build comments
# - Image resizing
# - Network access
#
# Usage:
#
#     sudo podman run --rm \
#                     --privileged \
#                     --volume /dev:/dev \
#                     --volume ${PWD}:/build \
#                     --env POLICY_NAME=bbb \

  ## Image Resizing
  #
  # Required.
  # Alternative values:
  #
  #  - reuse: fetch the image (.img) file, mount it and that's all. The size setting (below) is ignored in reuse mode.
  #  - new:   populate a rootfs (tarball with root file system).
