But yes, I agree that it is likely going to require some rethink. My personal position is that we have far too many degrees of freedom in zone configuration, for little useful benefit. We had similar goals and problems in supporting diskless clients, and we solved them by simply aligning the packaging breakdown with the configurations we supported. That may be required here, but most likely the way to such alignment is by reducing the options available in configuring zones, which I fear will be a tough discussion. Oh that we had been a bit more conservative on that front to start with. Dave
