Being mostly a FreeBSD freeloader (or a marginal contributor), I
shouldn't be complaining, and I am not, but permit me to make a
personal biased judgment: losing the ability to do a practically
important thing (a dynamic sound card tuning) which was available in
8, makes 9 a "not ready to be released" OS (GUI isn't relevant here.)

OK, I'll put my upgrades to 9 on hold... Thanks all for clarifying the

P.S. As an aside and IMHO:

Over the last year, I've been asking myself why I keep bothering with
FreeBSD when several Linux distros do everything painlessly out of box.

Obviously, I like FreeBSD general structure a lot, that's why.
FreeBSD won't miss me going back to Linux, but I may miss FreeBSD, so
I am still sticking on, but I see a lot of dangers to FreeBSD being a
meaningfully used platform, for various reasons (some of them have
been mentioned in several discussions on freebsd-stable.)  Breaking
POLA in a released OS, which I see with this sound card tuning issue,
doesn't add FreeBSD friends...
