# In order to make a base image as part of a Dockerfile, this container build uses

|
|
# podman build --security-opt=label=disable --cap-add=all --device /dev/fuse <...>
|

# NOTE: This container build will output a single giant layer. It is strongly recommended
|
|
# to run the "rechunker" on the output of this build, see
|
|
# https://coreos.github.io/rpm-ostree/experimental-build-chunked-oci/
