 No, I just sacrifice a lot of chickens.  A good way is to stuff truffle
 shavings under the skin and rub the chicken liberally with butter.  Then
 truss it.  Roast until golden brown & fully cooked (but not overdone!).

 Nice.  Does this mean it fully works now, i.e. you can access the files?
 
 Could you please test this patch (which I committed to -current).  I made
 two more changes and I'd like to be sure it works before issuing a pullup
 request to netbsd-4.
