222 Saying Y here includes support for SquashFS 4.0 (a Compressed
223 Read-Only File System). Squashfs is a highly compressed read-only
224 filesystem for Linux. It uses zlib compression to compress both
225 files, inodes and directories. Inodes in the system are very small
226 and all blocks are packed to minimise data overhead. Block sizes
227 greater than 4K are supported up to a maximum of 1 Mbytes (default
228 block size 128K). SquashFS 4.0 supports 64 bit filesystems and files
229 (larger than 4GB), full uid/gid information, hard links and
230 timestamps.
231
232 Squashfs is intended for general read-only filesystem use, for
233 archival use (i.e. in cases where a .tar.gz file may be used), and in
234 embedded systems where low overhead is needed. Further information
235 and tools are available from http://squashfs.sourceforge.net.
236
237 If you want to compile this as a module ( = code which can be
238 inserted in and removed from the running kernel whenever you want),
239 say M here and read <file:Documentation/modules.txt>. The module
240 will be called squashfs. Note that the root file system (the one
241 containing the directory /) cannot be compiled as a module.

243 If unsure, say N.

259 help
260 By default SquashFS caches the last 3 fragments read from
261 the filesystem. Increasing this amount may mean SquashFS
262 has to re-read fragments less often from disk, at the expense
263 of extra system memory. Decreasing this amount will mean
264 SquashFS uses less memory at the expense of extra reads from disk.
265
266 Note there must be at least one cached fragment. Anything
267 much more than three will probably not make much difference.
