	Note: In order to run this test, you must turn on "device mapper"
        component in kernel (it is under device drivers item when you
        run make menuconfig); and you must install userspace supporting
        files (libdevmapper and dmsetup). They are in the device-mapper
        package. You can download it from http://www.sistina.com. Follow
        the README/INSTALL file within the package to install it.
