"Again this is largely a presonal preference. I use ext3 as I have no use for xfs and reiser has some 'issues' yet. Let's put it like this, ext3 has always worked flawlessly and reiser has thrown me a few curveballs. Reiser works fine for alot of people however."

What exactly is XFS? Could You give more informations on the issues You had with reiser?
Thanks :P
