I see be0d16b0b05 bsdinstall: filter out disks that are unavailable from 
the list of options in ZFS

Not sure what that does however.

I am looking at :

So again nothing from yesterday until today that says a word about ZFS.

Right. I have seen it also but that was a long long time ago. Relatively
speaking and OpenZFS has never been an issue. I wish I had a serial
interface on the little laptop to boot to single usermode with and then
can look around and capture the output.

I have been through that before and usually it was just to import a
strange zpool from some other storage array onto some other machine.
I don't think that is needed here.

Yep. Let's avoid that.

I am going to see if I can build to commit 3587bfa797c on some other
hardware and have a look. Just because I am curious.
