+          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.
