What would be the main > issue: technical or licensing? 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. --=20 Pawel Jakub Dawidek http://www.wheel.pl pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
