 +        The ocfs2 filesystem now uses JBD2 for its journalling.  JBD2
 +        is backwards compatible with JBD.  It is safe to say N here.

+         Btrfs is a new filesystem with extents, writable snapshotting,
+         support for multiple devices and many more features.
+ 
+         Btrfs is highly experimental, and THE DISK FORMAT IS NOT YET
+         FINALIZED.  You should say N here unless you are interested in
+         testing Btrfs with non-critical data.
+ 
+         To compile this file system support as a module, choose M here. The
+         module will be called btrfs.
+ 
+         If unsure, say N.
