# To build this, run podman/buildah like this:
#
#     podman build --security-opt=label=disable --cap-add=all --device /dev/fuse \
#         --build-arg-file build-args.conf -v $PWD:/run/src . -t localhost/fedora-coreos
#
# Note: we should be able to drop the `-v $PWD:/run/src` once
# https://github.com/containers/buildah/issues/5952 is fixed.
#
# For development convenience, an `overrides/` directory in the context dir, or
# mounted at `/src/overrides` is supported:
# - The `overrides/rpm` directory can be a yum repo. Its packages take
#   precedence over those from remote repos.
# - The `overrides/rootfs` directory can contain files in a rootfs layout which
#   will be copied on top of the final rootfs.

# Overridden by build-args.conf. The value here is invalid on purpose.
