- select ZLIB_INFLATE
- help
- Saying Y here includes support for SquashFS 2.2 (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 64K.
-
- 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 filesystem 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.
