Yes, but if we were applying a sensible set of priorities then you don't need to care at all about the contents of the pci hole container, because the pci hole will be at a lower priority then mcfg; so you don't get into this odd corner case of "what happens if the high priority container turns out not to have anything there". -- PMM
