      # In general, if plugins are failing to properly load the
      # core issue will likely be one of two issues:
      #   1. manual modifications within ~/.vagrant.d/
      #   2. vagrant upgrade
      # Running an install on configured plugin set will most
      # likely fix these issues, which is all this action does.
