|
|
|
+ Saying Y here includes support for SquashFS 4.0 (a Compressed
|
|
|
+ Read-Only File System). Squashfs is a highly compressed read-only
|
|
|
+ filesystem for Linux. It uses zlib compression to compress both
|
|
|
+ files, inodes and directories. Inodes in the system are very small
|
|
|
+ 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.
|
|
|
+
|
|
|
+ If you want to compile this as a module ( = code which can be
|
|
|
+ inserted in and removed from the running kernel whenever you want),
|
|
|
+ say M here and read <file:Documentation/modules.txt>. The module
|
|
|
+ will be called squashfs. Note that the root file system (the one
|
|
|
+ containing the directory /) cannot be compiled as a module.

|
|
+ By default SquashFS caches the last 3 fragments read from
|
|
|
+ the filesystem. Increasing this amount may mean SquashFS
|
|
|
+ has to re-read fragments less often from disk, at the expense
|
|
|
+ of extra system memory. Decreasing this amount will mean
|
|
|
+ SquashFS uses less memory at the expense of extra reads from disk.
|
|
|
+
|
|
|
+ Note there must be at least one cached fragment. Anything
|
|
|
+ much more than three will probably not make much difference.
