I mentioned how xen-netback could do this as well, we'd keep or rename the flag I added, and then the bridge could would look at it and enable the root block if the flag is set. Stephen however does not like having the bridge code look at magic flags for this behavior and would prefer for us to get the tools to ask for the root block. Let's follow more up on that thread.
