No, it's definitely not USB specific. We're in principle happy with any type of block storage device what ZFS is happy with presuming it has enough capacity to function as a mirror to the full capacity of the device on which the existing root pool exists. So a second hard disk connected internally inside the system would be equally fine and even preferable, but that's probably not the common case since we expect most users to be laptop users who will be connecting external disks via USB, or maybe firewire or eSATA in a minority of cases. If the solution is capable of dealing with hotplug then presumably it should have no problem with permanently attached devices or devices that are attached before boot. Just for clarification I'll mention that we're not considering anything more exotic than a 2 way mirror configuration, and we will be assuming a single pool containing the root and user home directory filesystems with in it. Users running raidZ or multiple pools etc. would be beyond the scope of what we're aiming for. Thanks, Niall.
