The priorities plugin can be used to enforce ordered protection of repositories, by associating priorities to repositories. Theoretically, the repositories with the lowest numerical priority number have the highest priority. This is one of the method to prevents mistakes such as accidentally running yum upgrade with everything. This post cover the quick step to install yum-priorities on CentOS 6.3.
