Upon further consideration, the UI here is very inconsistent with other
options.
Actually I think the UI issues are more difficult and important than the actual
asize
change. To wit, no other nvlist options are set via vdev specification. I'd
much
rather see any such setting as normal options. In other words, the above code
specifies something like:
zpool create zwimming blocksize=4096 c0t0d0
rather than the more consistent:
zpool create -b 4k zwimming c0t0d0
