Linux installation with SquashFS support is the LZMA. It is the name of the compression algorithm that can be used to achieve better compression with SquashFS. SquashFS is a compressed, read-only file system for Linux that compresses files, directories, inodes, and supports block sizes up to 1 MB for greater compression. It is intended for use in constrained block or device memory systems like embedded systems, and for general read-only file systems. LZMA improves the performance of SquashFS by better compression, which provides at least 5% reduction of the file system. The downturn of this application is that the decompression is slower than zlib. To obtain a mksquashfs that supports LZMA requires editing of the squashfs-tools Makefile to enable LZMA support. There are comments in the Makefile that will assist inbuilding LZMA support into Mksquashfs/ Unsquashfs. Once the application has been built-in, LZMA support can be specified by using the –comp lzma option.
