# We're using a multistage Docker build here in order to allow us to release a self-verifying
# Docker image when built on the official Docker infrastructure.
# They require us to verify the source integrity in some way while making sure that this is a
# reproducible build.
# See https://github.com/docker-library/official-images#image-build
# In order to achieve this, we externally host the rootfs archives and their checksums and then
# just download and verify it in the first stage of this Dockerfile.
# The second stage is for actually configuring the system a little bit.
# Some templating is done in order to allow us to easily build different configurations and to
# allow us to automate the releaes process.
