  # By default rke creates bind mount:

  #   - custom bind mount
  #   - option to use volatile storage

  # Custom bind mount
  #
  # I did not find a proper way (in the docs) how to override the
  # defaults so I just abuse the extra_* args for the rke etcd
  # service. It means that it will create another mount point in the
  # container and you should use different pathnames than default...
  #
  # The custom bind mount is by default disabled.

  # On top of it (with or without custom mount) you can use tmpfs
  # as a volatile storage.
  #
  # CAUTION: This will create temporary filesystem (in the memory)
  # so if an etcd node will be poweroff then all etcd data will be
  # lost!!!

  # This is intended as an attempt to make deployment little bit
  # more faster...by default it is disabled.
