Providing a work-around in "sd" is great. We should do that, at least. But is it sufficient? What happens if I replace a mirrored drive with 512 byte sectors with one having 4k sectors? What if I want to plan ahead for that? Maybe in only some of my ZFS pools but not all? It would seem that a pool-level override for "ashift" might also be useful.
