Well, I'd point to one major factor with RHAT; they employ Stephen Tweedie, creator of ext3, and have been paying him to work on it for some time now. If they _didn't_ promote use of ext3, they would be very much vulnerable to the "won't eat their own dogfood" criticism.
True but frankly, they shouldn't. EXT3 has some serious issues. In fact if you are running a stock RH kernel before 2.4.20 you can destroy your PostgreSQL database with it.
Not to mention how slow it is ;)
That is not true see:XFS has been around a LONG time, and on Linux for a couple of years
now. Plus I believe it is the default FS for all of the really high
end stuff SGI is doing with Linux.
Ah, but there is a bit of a 'problem' nonetheless; XFS is not
'officially supported' as part of the Linux kernel until version 2.6,
which is still pretty "bleeding edge."

Again see above :)Until 2.6 solidifies a bit more (aside: based on experiences with 2.6.0, "quite a lot more"), it is a "patchy" add-on to the 'stable' 2.4 kernel series.
Do the patches work? As far as I have heard, quite well indeed. But
the fact of it not having been 'official' is a fair little bit of a
downside.
What is official?

I would (and do) trust XFS currently over ANY other journalled
option on Linux.
I'm getting less and less inclined to trust ext3 or JFS, which "floats
upwards" any other boats that are lingering around...
