Definitely the latter, but there some problems: - Some changes in OpenSolaris ZFS are very hard to port in short time, and when it takes a lot of time, new versions arrive and it is nice to get them too, etc. which makes whole process to take long time. Good example here is moving some functionality to Python, where we have to decided what to do about that without importing Python to the base system. - OpenSolaris ZFS is experimental and I don't think Solaris version is published anywhere. This means it needs extensive testing on our side, which of course takes time. - OpenSolaris changes are often not easy to understand. They have different commit rules than we have. Commit logs are not very helpful and multiple fixes are committed in one go, which makes it hard to separate individual changes if we just need a fix and not intrusive change that came along. I'm doing my best, but my time is limited. I see more and more people are interested in helping with ZFS, which is a very good sign I was waiting for for a long time:) It is of course still wonderful that we can use ZFS. All my servers and my laptop are running exclusively on ZFS at this point:) --=20 Pawel Jakub Dawidek http://www.wheelsystems.com pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
