I don't think "reassign everything" is any different from "honor what has been setup and (re)assign what's left or broken". "Reassign everything" is clearly allowed to produce the exact same result as "honor what has been setup and (re)assign what's left or broken". I claim any difference between the two is actually a fragile dependency on the Linux assignment algorithm that is likely to break as that algorithm changes. Or am I missing something? Bjorn
