Strategy to determine the preference order of image locations.
This configuration option indicates the strategy to determine
the order in which an image's locations must be accessed to
serve the image's data. Glance then retrieves the image data
from the first responsive active location it finds in this list.
This option takes one of two possible values ``location_order``
and ``store_type``. The default value is ``location_order``,
which suggests that image data be served by using locations in
the order they are stored in Glance. The ``store_type`` value
sets the image location preference based on the order in which
the storage backends are listed as a comma separated list for
the configuration option ``store_type_preference``.
Possible values:
* location_order
* store_type
Related options:
* store_type_preference
