My current main concern about XFS and reiser3 is writebacks. The default
mode for ext3 is "journal," which in case of power failure is more
robust than the writeback modes of XFS, reiser3, or JFS -- or so I'm
given to understand.
On the other hand, I have a UPS and it should shut down gracefully
regardless if there's a power failure. I wonder if I'm being too cautious?
