Tmpfs is a file system which keeps all files in virtual memory.
Everything in tmpfs is temporary in the sense that no files will be
created on your hard drive. The files live in memory and swap
space. If you unmount a tmpfs instance, everything stored therein is
lost.
See <file:Documentation/filesystems/tmpfs.txt> for details.

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