Dockerfile_build

# This file describes an image that is capable of building Flux.

# "Wait," you ask. "What's going on here?" Rather than handling rustup validation
# and verification, we can list the rust container as a prior build stage, and
# then pull in the artifacts we need. There is an added benefit that tagged versions
# also include minor releases, so 1.2 includes 1.2.1 and so on, for bugfix releases.
