Again, forgive my ignorance if I don't understand how this works for all storage types, but it seems that when a template is first used in a cluster we copy the template to primary storage first and use that for all subsequent. Should we add an enhancement to be able to tag templates that should be cached on primary vs ones that should be copied direct from secondary storage whenever used?
I'm thinking about scale, if I've got 20 templates that are used a lot by everyone, then I want those cached, but if my users are making 1000 templates and only use each once or twice, I don't want them to go to my primary storage. Especially with CLVM or another raw style storage where we actually use the whole physical size of the template.
