I could have chosen to not specify the full path for the ip command and for that
matter all the external scripts I invoke from the KVP daemon. Do you mind if I
submitted a patch to get rid of the absolute paths in this code.
Stephen's suggestion is clearly simpler (I don't need to invoke awk to filter what
we want). Steve, I could make this change as well as an additional patch.
