So long as we can't use RAIDZ on the root pools, I think it is in fact a good idea to keep them separate, because the fault boundary in ZFS is at the pool level - if the pool is destroyed (either by hardware failures, software bugs, or administrator error), everything in it is toast. Losing both your OS and your user data seems like an exponentially worse disaster than either by itself. Dave
