"While not yet stabilized, the Btrfs file-system was merged into
the Linux 2.6.29 kernel and is poised as the Linux competitor to
Sun's famed ZFS file-system. There is also open-source work
underway in supporting Microsoft's exFAT file-system on Linux. On
top of all of that, there is also the Tux3 file-system.
"The Tux3 file-system was last talked about here in late
November when they were moving from their FUSE module to doing a
kernel port of this file-system that succeeds the never-released
Tux2. Now, however, the Tux3 file-system is making it a bit
further. Last week the Tux3 developers were successful in using
Tux3 as the root file-system. Their initial benchmarks are also
fairly promising and according to Daniel Phillips the file-system
has been "exceptionally stable" for him."
