[deleted stuff on XFS]
Yes, I noticed XFS seems to have quite a few people with good 
experiences.  That's another one I might consider.  I was a little 
reluctant because I've also seen (not in this list) people saying it ate 
their data.  Of course, a lot of people said that about reiserfs too, 
and probably every other file system...
