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.
