  # GitHub disables a repository's scheduled workflows after 60 days without
  # activity, and the only thing that happens here is this workflow pushing with
  # GITHUB_TOKEN - which does not count. Left alone the daily sync switches
  # itself off and the mirror silently goes stale, taking phytium kernel builds
  # with it. This re-arms the schedule on every run, the same way
  # armbian/docker-armbian-build does.
