The correct behavior regarding boot time auto import of pools is to honor that property as found on the pool the boot filesystem was on, so that other pools sharing the same cachefile path will be imported. Multiple cache files and pools not actually listed in a cachefile are valid scenarios for pools. Just want to express my complete agreement. -- Andriy Gapon
