Yes, exactly.

grub-probe fails because of incompatible zpool features that are enabled
by default.  The error message is not very helpful and could be improved.

Instead of creating a zpool like this:

> zpool create -m none spool mirror /dev/sde /dev/sdf

You must use the -d option.  You can still enable LZ4 because GRUB 2.02
has support for it:

> zpool create -d -o feature at lz4_compress=enabled -m none spool mirror /dev/sde /dev/sdf

Where did you find these daily installer builds with ZFS support?  And
what instructions did you follow?  (The documentation should be updated
with the information above).

I'll be committing a fix for #775395 in partman-zfs soon.
