184	help
185	  NILFS2 is a log-structured file system (LFS) supporting continuous
186	  snapshotting.  In addition to versioning capability of the entire
187	  file system, users can even restore files mistakenly overwritten or
188	  destroyed just a few seconds ago.  Since this file system can keep
189	  consistency like conventional LFS, it achieves quick recovery after
190	  system crashes.
191
192	  NILFS2 creates a number of checkpoints every few seconds or per
193	  synchronous write basis (unless there is no change).  Users can
194	  select significant versions among continuously created checkpoints,
195	  and can change them into snapshots which will be preserved for long
196	  periods until they are changed back to checkpoints.  Each
197	  snapshot is mountable as a read-only file system concurrently with
198	  its writable mount, and this feature is convenient for online backup.
199
200	  Some features including atime, extended attributes, and POSIX ACLs,
201	  are not supported yet.
202
203	  To compile this file system support as a module, choose M here: the
204	  module will be called nilfs2.  If unsure, say N.
