[Openstack] image_service=nova.image.s3.S3ImageService???

[Lorin Hochstein]

I'm updating the documentation for this page: 
http://docs.openstack.org/trunk/openstack-compute/admin/content/configuring-compute-to-use-the-image-service.html

My question is: is there any use case where you would configure nova to do:

image_service=nova.image.s3.S3ImageService

Looking at the code, it seems like this would not even work. The S3ImageService 
defers several methods (e.g., index, create, delete) to the image service so by 
the image_service flag, so you'd get an infinite recursion. It appears like 
theS3ImageService can only be used as a wrapper around the default image 
service, and can't be a default image service on its own.

I'm going to zap this as a valid option from the documentation (unless someone 
sets me straight here).

Take care,

Lorin

Correct, S3ImageService is a wrapper, you can't specify it in the image_service 
config option.
