Public bug reported:

The Install Guide for Glance (Zed) is:

1) outdated; still using configuration fields "stores" and "default_store" in the [glance_store] config group 
 (which are deprecated - removed in Rocky) and does not show good examples of how to properly use the newer "enabled_backends" field under the [DEFAULT] config group.  Unfortunately the Glance Configuration Reference also doesn't supply enough information on how to use the "enabled_backends" field.  For example, what syntax is expected for the dictionary?,  is the dictionary a string:string key value pair?  What kinds of "type" "values" are acceptable and how are they used elsewhere (it says the key is used later in the "default_backend" field, but the value is never explained, or illustrated with a good example in the documents.

2) should be improved to explain what "MY_SERVICE", "MY_PASSWORD" and
"ENTRYPOINT_ID" should be changed to in the [oslo_limit] config group
values being assigned to the various config fields.  I eventually
figured these should be the "glance" user and user password set earlier
but I'm still guessing really.  And as far as the ENTRYPOINT_ID I
figured it was the hash ID of the glance service.  Again, another guess.
And if so, why not use the glance service name? Those terms, MY_SERVICE
etc etc are not explained/referenced anywhere else in the Glance install
document (really confusing since they appear out of nowhere).  They look
to be simply copy pasted from some of the oslo documentation found
elsewhere I think.
