+ 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.
