 103
 104           Everything in tmpfs is temporary in the sense that no files will be
 105           created on your hard drive. The files live in memory and swap

 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.
