Slashdot comments on an article stating that Mac OS X 10.2.2 will have an optional journaled file system.
At a speed hit of 10-15%, the JFS will give the system a file transaction history. BeOS used this and it was GREAT. After a crash, a 10 second rebuild is all that was needed to fix the disk.
Oh yeah, yeah, the same guy that wrote the Be’s JFS wrote this one!
Journaling is cool, but the mac does not need an even slower file system 🙂
