writes to recommend his editorial overview of the past, present and future of Linux file systems
: ext2, ext3, ReiserFS, XFS, JFS, Reiser4, ext4, Btrfs, and Tux3. "In hindsight it seems somewhat tragic that JFS or even XFS didn't gain the traction that ext3 did to pull us through the 'classic' era, but ext3 has proven very reliable and has received consistent care and feeding to keep it performing decently. ... With ext4 coming out in kernel 2.6.28, we should have a nice holdover until Btrfs or Tux3 begin to stabilize. The Btrfs developers have been working on a development sprint and it is likely that the code will be merged into Linus's kernel within the next cycle or two."
