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 3.1 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 .
