NetBSD ZFS compatibility with other OSs

[Rocky Hotas <rockyhotas%firemail.cc@localhost>]

Hi all!
ZFS is one of the major updates in NetBSD 9.0. As far as I understood,
it is an implementation of OpenZFS, as Linux and FreeBSD already have
done. Also MacOS should use ZFS.

Is a ZFS filesystem created inside NetBSD 9.0 compatible with these OSs?
At least NetBSD, FreeBSD and Linux used code from the OpenZFS project.

In a simple example, assume that I created a pool with NetBSD 9.0. Am I
able to export it, and to import it on FreeBSD and/or Linux, obviously
without data loss? And what about re-importing it on NetBSD?

Bye!
