we always do ZFS receives from a local disk, after we had the system
with the ZFS drives die in a big way when the link went down.

playing up at the time, but we never want to have to fix that type of
error again ... ghostly snapshots that can't be used/destroyed, disks
that never rebuild in mirrors ... *shudder*.
