    Ultimately something like Reiser will win over UFS, but performance
    figures aren't the whole picture.  Most of the bugs have been worked out
    of UFS and the recovery tools are extremely mature.  Only a handful
    of edge cases have been found in the last decade.  Nearly all the bugs
    in the last few years have turned out to be buffer cache or VM bugs
    rather then filesystem bugs.  ResierFS has a long way to go before it
    can be safely used on production systems.  Linux, having just moved
    to a totally new VM system also has a long way to go (and, for the same
    reason, FreeBSD-5 has a long way to go before it can safely be used in
    production).  When Reiser starts to get close, I'll be the first one
    to port it to FreeBSD :-)

    Consider for a moment the development roadmap for UFS, EXT2FS, and
    REISERFS.  It took UFS and its supporting tools years to get as good as
    it is for production purposes.  It has taken EXT2FS a number of years
    to reach where it is.  ReiserFS is new, and it is going to be a while.
