Hi Pawel, I totally understand the time commitment. I know several of the primary ZFS committers on OpenSolaris, and realize that it's easier for them because they're paid by Sun to work on it. Thank you very much for your effort on making it work inside of FreeBSD. It's giving all of us that made the jump to OpenSolaris a life raft. To be honest the two things that are critical to our company on OpenSolaris are ZFS and Zones. -J On Tue, Apr 20, 2010 at 8:23 AM, Pawel Jakub Dawidek <pjd@freebsd.org> wrot= e: > On Tue, Apr 20, 2010 at 07:24:53AM -0600, Jason J.
