OpenZFS doesn't have the same ashift optimization logic that FreeBSD

integrated downstream.
So currently all pools created with OpenZFS will use 512 bit
alignment, at least if the underlying storage device uses 512bit
sectors (which most drives tend to do)?
If this is the case, it feels like a pessimisation.

The vdev ashift optimizations from FreeBSD were put in OpenZFS before
the import into base. That sysctl does work now.
Ugly hack w/ geom_noop required again?
I believe you can do `-o ashift=` with zpool create/add now.
