A lot of changes to the Squashfs filesystem have been made under the bonnet (hood), to improve compression. Squashfs 2.0 has added the concept of fragment blocks and has increased the block size to 64K. This achieves a 5 - 20% compression saving, and allows Squashfs to achieve better compression than Cloop while retaining the I/O efficiency of a compressed filesystem. In addition, the maximum number of UIDs and GIDs has been increased to 256. This allows Squashfs to better support live CDs. For a description of fragment blocks and the other changes, please go to the project page http://squashfs.sourceforge.net. Regards Phil Lougher
