This is not entirely correct. ZFS is only under the CDDL license and
it has been ported to FreeBSD.

I wonder how they handled the license issues? I thought that if you
combined stuff that was BSD licensed with stuff with a more restrictive
license the result was under the more restrictive license. thanks for
the info.
The CDDL is not a restrictive license like GPL, it is based on the MIT
license so it can be used with BSD stuff without problems. There are
lots of discussion going on (read: flamewars) on the opensolaris lists
about how it can/should it/will it be integrated into linux.
here's a link about the GPLv2 stuff for zfs

That title is fairly misleading as it's only some read-only bits to be
able to boot off ZFS with grub.
