Can you reliably reproduce this?
"need more than 0 values to unpack"? That's strange, isn't it? I'd assume it would be one value - the exception instance. But maybe my understanding of exception handling is incomplete.
Anyway, here's a suggested patch for execWithRedirect:
diff --git a/iutil.py b/iutil.py
index 0d7faed..7d354b7 100644

+ except OSError, e:

Haven't tried to reproduce yet - restarting the install now.
Hrm. Can't reproduce so far. Might be some kind of unreliable race with udevadm or something? Or maybe I just got a bad image? Who knows. I'll keep trying.
Well, I've pushed your patch above for all places where we catch OSError. I did the same thing in rhpl a little while back and haven't seen any new complaints. Hopefully this will take care of it.
