Allow other device types for testing; this allows to test on a larger variety of devices. Option --dev=[loop|lvm|ram] selects loop device (default), lvm, and ram disk, respecively. To use RAM disks with DDF, the kernel parameter ramdisk_size=65536 must be used. For LVM, use --volgroup=<vg> to specify the name of the volume group in which the test LVs will be created.
