I don't know if there are licensing issues, probably yes if we would
like to add ZFS support to our standard loader.

The biggest problem I see is lack of motivation on my side. Really. Why
someone would like to keep kernel on ZFS so much? This would be a huge
amount of work, I expect, and what we get in turn? On Solaris you can
only boot from a single-disk pool or from a mirrored pool. Is it really
worth the effort for us? I much more prefer to spend the time working on
something more useful than that and keep my small /boot/ file system
protected by gmirror on UFS - with this approach there are no
limitations - we can keep our root file system on compressed RAID-Z
pool.

Of course if someone is willing to try working on this, I'm happy to
help.
