  # Thanks to pack-objects cache, clone strategy should behave faster than fetch
  #   so we pick "clone" as default git strategy
  # Shiny runners by default remove the CI_PROJECT_DIR every time at the beginning of one job
  #   and clone with a --depth=1
  # Brew runners will fetch from locally mirror first, and cache the local CI_PROJECT_DIR
  # In conclusion
  # - set GIT_STRATEGY: "clone" to shiny runners
  # - set GIT_STRATEGY: "fetch" to brew runners
