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 3.3 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 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. ++ ++ If unsure, say N. ++ ++config SQUASHFS_EMBEDDED ++ ++ bool "Additional option for memory-constrained systems" ++ depends on SQUASHFS ++ default n ++ help ++ Saying Y here allows you to specify cache size. ++ ++ If unsure, say N. ++ ++config SQUASHFS_FRAGMENT_CACHE_SIZE ++ int "Number of fragments cached" if SQUASHFS_EMBEDDED ++ depends on SQUASHFS ++ default "3" ++ help ++ By default SquashFS caches the last 3 fragments read from ++ the filesystem.
