#
# The stage0 binaries are typically baked into VM images and container
# images and are NOT downloaded per build or VM/container start-up.
# The only reason we upload them to GCS is because that's where the
# automated VM/container creation scripts download them from.
#
# The notable exception is our Mac VMs on MacStadium. In those cases,
# the images actually do download the stage0 binary on start-up.
