--- Comment #8 from Juan Lang juan_lang@yahoo.com 2010-01-08 12:31:45 --- The patch got the "Pending" status, which probably means it needs a test case. It did anyway.
Porting the Python test would probably be a start, although the machine should be checked for whether it has a MAC address before checking whether the most significant bit of the MAC address field of the generated UUID is cleared. The Python test should do the same, of course.
