On the other hand, it's probably undesirable to make it so complicated that people can't fit the rules into their heads. One idea is to set up a set of linear constraints and optimize for some simple function, though even that might be overkill. At the very least, it should know when it can't find a feasible solution (``/usr can't be that small!'') and give up.
