# so skopeo cannot copy / inspect buildah images, but, found this gem in the
# podman man-page:
#
# Podman uses Buildah(1) internally to create container images. Both
# tools share image (not container) storage, hence each can use or
# manipulate images (but not containers) created by the other.

# so i have some test images created with buildah, and I can see them with podman
# my goal is to figure out a way to copy them to another system(s) and use them
# as part of a build system I am working on for some products
