Squashfs is a highly compressed read-only + filesystem for Linux. It uses zlib, lzo or xz 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 4.0 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 tools are available from http://squashfs.sourceforge.net. + +config SQUASHFS_XZ + bool "Include support for XZ compressed file systems" + default y + depends on FS_SQUASHFS + select XZ_DECOMPRESS + help + Saying Y here includes support for reading Squashfs file systems + compressed with XZ compression. XZ gives better compression than + the default zlib compression, at the expense of greater CPU and + memory overhead. + + XZ is not the standard compression used in Squashfs and so most + file systems will be readable without selecting this option. |
