+          Saying Y here includes support for SquashFS 4.0 (a Compressed

+          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 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

+          will be called squashfs.  Note that the root file system (the one
