I don't think this is really a separate versioning issue but is more something that should be added to the zpool version checking. If we find that there is an existing pool we need to get it's zpool version and check that against the bits we want to install to make sure that they are capable of using that pool. What I'm not sure of with this issue is, if this pool version check fails, should fail the install at that point or put an install on a pool that we know it can't use. If the pool version is newer than the bits we're installing can support I would say that we should fail at this point because we know it won't work. I'll add this to the zpool checking part of the spec.
