Comment 1 for bug 1496822

I think we can enhance the description of the parameter to explain users that this option just stores instance_uuid but it doesn't use the instance as the basis for the image. AFAIU, that's the goal of the field.
So I think it is more reasonable because instance_uuid is part of image schema and can be used by some users. I would like to avoid partial fix when we will delete the description from the help but instance_uuid will be part of the schema. I will propose the fix soon, so we can also discuss this in gerrit.
