Is there a way to identify if an rpm package is unused, or how much it is used?

 

I would like to reduce my load time by removing unused packages in my kickstart, but do not want to cause problems for users on active systems by guessing which ones are not necessary (I load everything with kickstart now).  If I could find the packages are not used I could start by excluding them from a load and be fairly certain my users would not be impacted.
