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.

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."  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.

I'm getting less and less inclined to trust ext3 or JFS, which "floats
upwards" any other boats that are lingering around...
