Eric,

You do understand it correctly and I agree with what you are saying. I 
cannot use your suggestion, however, because the requirement is that at 
any given time the textual representation of the system is stable, 
meaning no unresolved dependencies. So, I cannot have an unstable 
textual representation and wait until actual install time to get things 
resolved by yum or other tool.
