You're talking about 'pool=default', right? I agree. What term should be use instead for the root of the tree?

'root=default'? 'tree=default'?

I think this is only a matter of the default types, so it should be easy to fix.. just updating docs, basically..

Since it's a hierarchy of nodes, I'd vote for "root." Also, the term "bucket" is confusing, because we use that term with the S3 API. CRUSH hierarchies, as I understand them, are nodes and leaves, and so I prefer those terms to "bucket."
