According to the OpenSolaris Licensing FAQ[1], the CDDL[2] does not
impose requirements on other objects linked with a covered source
file.  So a port of ZFS to NetBSD (as an LKM, or possibly as an
optional contrib/sys thing?) seems like it wouldn't be a legal problem.

    See, in particular, the section contrasting it with the GPL
    and the following one on patents.

[2] http://www.opensolaris.org/os/licensing/opensolaris_license/
    See, in particular, sections 3.6 and 1.9.

This is, however, almost certainly the wrong list for this,
and I am of course not a lawyer.
