And we are back at the start. The "problem" is that I really like consistency.
So when "zpool status" throws that ominous message at me - any you have
to admit that it is phrased like a warning - I want simply to get rid of that.
After a reasonable after-update grace period.

But during our discussion I have come to wonder:

- I upgrade from 13.0 to 13.1, I do a "zpool upgrade" afterwards, I also upgrade the boot loader

- I install 13.1 with ZFS

What is the difference? Shouldn't these two imaginary systems be absolutely the same in terms
of ZFS features, boot loader, and all that?

Kind regards,
Patrick
