I dont really need crossplatform, but was curious. You can also use the mkuzip command (and the geom_uzip kernel module) in the base system, which generates the same file format as Linux cloop files but is much more memory-efficient than cloop's create_compressed_fs program. I don't think there is any Windows support for mounting compressed filesystem images (I can't even find Windows tools for mounting filesystem images in general apart from daemontools which only does ISO images). -- Dan Nelson dnelson@allantgroup.com
