This test probably deserves some more explanation. InitPartition creates a single partition (/dev/sda1) for the test environment. The test code then zaps the MBR partition table, overwriting the table and the signature with all zeroes. This Wikipedia page is a helpful reference: https://secure.wikimedia.org/wikipedia/en/wiki/Master_Boot_Record We then tell the kernel to reread the partition table, and list the partitions (which, being zapped, we expect to be an empty list).
