Saying Y here includes support for SquashFS 4.0 (a Compressed

+ filesystem for Linux. It uses zlib/lzo 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
