That article does a good job describing RFS and contrasting it to ext2fs, but it leaves several questions left un-answered in relation to ufs. RFS might be faster or more stable than ufs, but there's no way to assume that based on it's superiority to ext2fs, since ufs is also far superior to ext2fs (I'm assuming ufs with softupdates turned on here). The ability to store data within the b-tree seems to be a valuable feature. In fact, using a b-tree instead of other forms of metadata storage is very interesting; it's similar to how most database engines impliment indexes. I'm not so convinced that a journal is the greatest thing in the world, though. I think it makes much more sense to do what softupdates do.... perform updates to the filesystem atomically and in a manner where the metadata is always written first. My $0.02, dB!
