What I was saying is that the writers of postinstall scripts should be 
mindful that their scripts are re-runnable. And for the few instances 
where a postinstall script relies on things like the non-existence of a 
previous state that they should perhaps provide a option, say 
-reinstall, that would set the situation as if it was a new install.
