I've had a read of the patches and I agree with Junio's comments on the
second patch. I'd really like us to avoid sudo in the tests if we can as
it causes a lot of problems. Just to let you know I'm going to be off
the list for the next couple of weeks, so I wont be looking at these
patches in that time.
Best Wishes
