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.

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