Linux: Btrfs, File Data and Metadata Checksums
,----[ Quote ]
| Chris Mason announced an early alpha release of his new Btrfs
| filesystem, "after the last FS summit, I started working on a new
| filesystem that maintains checksums of all file data and metadata." He
| listed the following features as "mostly implemented": "extent based file
| storage (2^64 max file size), space efficient packing of small files,
| space efficient indexed directories, dynamic inode allocation, writable
| snapshots, subvolumes (separate internal filesystem roots), checksums on
| data and metadata (multiple algorithms available), very fast offline
| filesystem check".

ZFS Filesystem for FUSE/Linux
,----[ Quote ]
| ZFS is an advanced modern general-purpose filesystem from Sun
| Microsystems, originally designed for Solaris/OpenSolaris.
|
| This project is a port of ZFS to the FUSE framework for the

Access frees database filesystem for Linux devices
,----[ Quote ]
| Access/PalmSource has released an SQL-based filesystem for embedded
| devices under the LGPL (Lesser General Public License). Libsqlfs
| implements a POSIX-style hierarchical filesystem as an SQLite database
| file, and was originally developed to provide a registry of system and
| application configuration data for mobile phones, according to
| Access.

Mount Wikipedia As A Virtual Filesystem
,----[ Quote ]
| Thanks to WikipediaFS, Wikipedia fiends tired of reloading pages
| in the browser can now, provided they?re using Linux, mount the
| site as a virtual filesystem.
|
| WikipediaFS is a mountable Linux virtual file system that enables
| you to view and edit Wikipedia (or any Mediawiki-based site)
| articles as if they were real files.

Linux: LogFS, A New Flash Filesystem
,----[ Quote ]
| In contrast, Jorn compared his new LogFS, "LogFS has an on-medium
| tree, fairly similar to Ext2 in structure, so mount times are O(1).
| In absolute terms, the OLPC system has mount times of ~3.3s for
| JFFS2 and ~60ms for LogFS."

Why so many filesystems for Linux? What?s the difference?
,----[ Quote ]
| * EXT3
|
| * Most popular Linux file system, limited scalability in size and
| number of files
| * Journaled
| * POSIX extended access control
|
| EXT3
| file system is a journaled file system that has the greatest use in
| Linux today. It is the "Linux" File system. It is quite robust and
| quick, although it does not scale well to large volumes nor a great
| number of files. Recently a scalability feature was added called
| htrees, which significantly improved EXT3's scalability.
|
|
| [...]
|
| * FAT32
|
| * Most limited file system, but most ubiquitous
| * Not Journaled
| * No access controls
|
| FAT32
| is the crudest of the file systems listed. Its popularity is with its
| widespread use and popularity in the Windows desktop world and that it
| has made its way into being the file system in flash RAM devices
| (digital cameras, USB memory sticks, etc.). It has no built in
security
| access control, so is small and works well in these portable and
| embedded applications. It scales the least of the file systems listed.
| Most systems have FAT32 compatibility support due to its ubiquity.
