I have one question to make sure about the guidelines for future. I've
been using ZFS on my arm64 machine for a while (a HEAD snapshot from
~July + custom newer kernels for development) - after trying the
vanilla kernel after Nov 10 OpenZFS update I could no longer access
the root partition (even after returning back to the kernel that had
previously worked).

I repeated the same thing with Nov 4 snapshot:
- Install system with ZFS
- Try kernel binary with updated OpenZFS - lose access to root partition.

Is such behavior expected? If yes, is it recommended for the ZFS case
to use kernel and the world only from the same baseline?

Best regards,
Marcin
