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.
