-# This container build uses some special features of podman that allow
-# a process executing as part of a container build to generate a new container
-# image "from scratch".
-#
-# This container build uses nested containerization, so you must build with e.g.
-# podman build --security-opt=label=disable --cap-add=all --device /dev/fuse <...>
-#
-# # Why are we doing this?
-#
-# Today this base image build process uses rpm-ostree.  There is a lot of things that
-# rpm-ostree does when generating a container image...but important parts include:
-#
-# - auto-updating labels in the container metadata
-# - Generating "chunked" content-addressed reproducible image layers (notice
-#   how there are ~60 layers in the generated image)
-#
-# The latter bit in particular is currently impossible to do from Containerfile.
-# A future goal is adding some support for this in a way that can be honored by
-# buildah (xref https://github.com/containers/podman/discussions/12605)
-#
-# # Why does this build process require additional privileges?
-#
-# Because it's generating a base image and uses containerization features itself.
-# In the future some of this can be lifted.
