Nice, do you also have an mksquashfs with lzma support?
Yes, in Squashfs CVS (http://sourceforge.net/projects/squashfs/develop).
You'll need to edit the squashfs-tools Makefile to enable LZMA support.
The comments in the Makefile should, hopefully, explain how to
build LZMA support into Mksquashfs/Unsquashfs.
Once built-in, LZMA support can be specified using the -comp lzma option, i.e.
mksquashfs dir dir.img -comp lzma
Unsquashfs doesn't need any extra options, it automatically detects which
compression has been used.
You can tell which compression algorithms Mksquashfs/Unsquashfs support by
just typing the command on its own (i.e. mksquashfs, or unsquashfs). The
(de-)compressors available are displayed at the end of the output.
