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. | ||

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. | ||
