Can you please update to this version? Perhaps it is a final release, don't know how you created the last release. 4.0 5 APR 2009 Major filesystems improvements 1. Kernel code improvements: 1.1 Fixed little endian layout adopted. All swapping macros removed, and in-line swapping added for big-endian architectures. 1.2 Kernel code substantially improved and restructured. 1.3 Kernel code split into separate files along functional lines. 1.4 Vmalloc usage removed, and code changed to use separately allocated 4K buffers 2. Unsquashfs improvements: 2.1 Support for 4.0 filesystems added. 2.2 Swapping macros rewritten. 2.3 Unsquashfs code restructured and split into separate files. 3. Mksquashfs improvements: 3.1 Swapping macros rewritten. Fixed little-endian layout allows code to be optimised and only added at compile time for big endian systems. 3.2 Support for pseudo files added.
I bumped sys-fs/squashfs-tools to 4.0 and removed the older CVS snapshot ebuild.
