As one who has gone through that upgrade on head/, stable/9/, and stable/8/, I could not agree more. This is why I was a bit confused about vfs.zfs.version.spa, to be honest - I did not see any "version changes" associated, but only user reports about "old zfs tools" not working. Thanks for all the info. Glen
