Agreed. But you have to *know* the drive serial number or UUID to do 
that. And there is, of course, a high probability that you will not have 
that information available.

(Ha! With Captain Murphy's thumb on the scale the probability is 
exactly: 1.000000. )

The advantage of marking the actual disk is that you only need remember 
which way you installed...extra partition on sda/sata 1 or not.
