What's the significance of this set of package names?  I couldn't
immediately spot an obvious reason why these particular recipes were
getting special treatment.
 
It seems particularly weird to have update-rc.d in there since that is
an allarch recipe and (one hopes) isn't going to change much under
multilib.
