|  | 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. |
