 == Package management system versus package manager == 

 I know the difference between an installer and a package management system, this does not concern that. But at the top of the article it says ""a package management system is sometimes incorrectly referred to as a package manager or a system install manager."" A package management system and a package manager are the same thing. RPM is called the ""RPM Package Manager,"" and is a package management system. I'm taking the part that says it's incorrectly referred to as a package manager out.   "
