# SUMMARY: basic sanity check of --download-only and --cache-only

# To truly test --download-only/--cache-only, we need to set up an ostree remote
# and a remote yum repo. We could use the same ostree repo here since
# my-remote:my-ref != my-ref, but let's be extra realistic by having two
# completely separate repos.

# seed with a first package so we have a valid repo there
