I find that *very* counter productive for bindings that go to the same
node. You have a description of a node, and then suddenly there you
have another file with another description of the same node. Totally
awesome.

Also how do you plan to write partitioning schemes with parameters
like with non-zero offset of the partition table.

Thanks
