Throw in the softupdates technology, and you have the upside of journalling, without the downside of journalling. No. I'm not going into details, first because I'm not qualified, and second, others already have. Was it Matt? I don't recall now, who made the observation, [sic] "Why does the Linux camp get so excited about the support for so many filesystems? Pick one, and make it the best you can.". In a recent thread about NFS performance, one post mentioned that ReiserFS died quite early in the test. If it's that much better, why didn't it survive that much better? The one thing that journalling FSes deliver that FFS with softupdates doesn't right now is a 'fsck'less boot after an uncontrolled shutdown. I have read that the Project has this on their TODO list. I know a post like this one can start a flameware for statements made without facts to back them up, but the facts exist, have been pointed out many times, and I don't want to mis-quote or mis-appropriate them. > Those are just my $0.02.
