I agree. FreeNAS based on FreeBSD we can run and not worry about all the issues we have with Linux and Windows. It is truly a breath of fresh air in the world of computing.This is critical. I'm not interested in running my servers on Linux. I choose FreeBSD for my servers for a reason (router, NAS, and other servers including internet-facing ones).
I hope that you never lose the FreeBSD version, and that these other efforts don't dilute the resources available to give due attention to the FreeBSD-specific builds. I can think of other projects that, after spreading themselves more thinly, basically gave the finger to their FreeBSD version. So my concerns are based on real life and not hyperbole.
