There's no guarantee for backwards compatibility right now with squashfs. Outside of the installer it really shouldn't be used.
Unless you're doing embedded development, or reverse engineering work, where you need to mount squashfs file systems over loopback. Sigh, I guess I will have to keep that old 2.6.17 kernel around then.
