This reminds me of a question.  I have a laptop with two interfaces
(wired and wireless).  I would like to have the machine get the same
address whichever interface it uses.  I tried

      host hostname
      {
      fixed-address xxx.xxx.xxx.xxx;
      hardware ethernet xx:xx:xx:xx:xx:xx;
      hardware ethernet yy:yy:yy:yy:yy:yy;
      }

and I thought it used to work, but now only yy:yy:yy:yy:yy:yy is assigned
the fixed address.  Instead, xx:xx:xx:xx:xx:xx gets a pool address.
Should this work, and if not, is there a way to accomplish what I want?

Thanks.
