I am interested in squashfs 4 and lzma too ...

SquashFS version 4.0 is included in Linux Kernel 2.6.29. LZMA support is not there, but since squashfs made its way to the kernel, LZMA compression algorithm will follow it sooner or later. What does it mean for this project (squashfs-lzma.org)? There is no longer any interest in developing separate patches against squashfs 4.0. If you need it, you'll most likely find it in official Kernel 2.6.30 or so. So don't worry, be happy

For now, lzma3 compression is in the kernel. lzma4 (xz) is in way to be in the kernel too.
But for now, there is no way to link a squashfs4 with either of these compression scheme : only huffman zip (gzip) is avaible.
A general interface for compression is in progress for squashfs4 and some changes are done to xz to make it able to be parallelized. Once this is done, it could be possible to use squashfs4 with xz for example.
But for now, we must wait, and so to use a well-compressed readonly filesystem, squashfs3+lzma patch (disabling squashfs4) is the only option.

What does this all mean? How is the state of squashfs (3 or 4) with lzma in salix? Which packages are needed?

None.
You cannot mount squashfs filesystems compressed with lzma. Use can use qquashfs 4 (it's a module in Salix/Slackware) only with uncompress squashfs.

The Salix Live CD to come use a patched slackware kernel and use Squashfs 3 + lzma. Squashfs 4 has been deactivated.

Okay nice to read about progress.
