- Stores not just filenames but the files themselves in a balanced
- tree. Uses journalling.
-
- Balanced trees are more efficient than traditional file system
- architectural foundations.
-
- In general, ReiserFS is as fast as ext2, but is very efficient with
- large directories and small files. Additional patches are needed
- for NFS and quotas, please see <http://www.namesys.com/> for links.
-
- It is more easily extended to have features currently found in
- database and keyword search systems than block allocation based file
- systems are. The next version will be so extended, and will support
- plugins consistent with our motto ``It takes more than a license to
- make source code open.''
-
- Read <http://www.namesys.com/> to learn more about reiserfs.

+ Saying Y here includes support for SquashFS 4.0 (a Compressed

+ and all blocks are packed to minimise data overhead. Block sizes
+ greater than 4K are supported up to a maximum of 1 Mbytes (default
+ block size 128K). SquashFS 4.0 supports 64 bit filesystems and files
+ (larger than 4GB), full uid/gid information, hard links and
+ timestamps.
+
+ Squashfs is intended for general read-only filesystem use, for
+ archival use (i.e. in cases where a .tar.gz file may be used), and in
+ embedded systems where low overhead is needed. Further information
+ and tools are available from http://squashfs.sourceforge.net.

+ inserted in and removed from the running kernel whenever you want),
