      # Use Github Actions to cache RPMs by date. This can save a couple minutes
      # in the run, which is nice. The cache contains the Yum sqlite database,
      # and the downloaded RPMs.
      #
      # A cache miss results in getting the most recent cached data (e.g. from
      # yesterday). The runner will check the repo metadata and get the updated
      # data, and delete any stale data, so after the run completes, the
      # testdata can be cached for future runs.
      #
      # On a cache hit, the test runner will still check the yum repo metadata,
      # and if it differs from the cached data, it will clear and download it.
      # So a cache hit isn't guaranteed to speed things up, but kernel packages
      # aren't usually updated _that_ frequently.
