There are 2 things that are being worked on : the spacewalk community has scripts that will parse this info from within packages and present it in a usable state. And secondly, I've been working on a yaml based script that can do something similar and hope to have it in a usable state soon ( for where soon ~ a month or so ). The other option you have, if you fancy a bit of code writing, is to use the yum-changelog plugin to parse what comes through the package manifests and make decisions on things that way - keep in mind that its a maze and you will need some level of smartness. Its not as drastic an issue on CentOS as it can get in other distro's but its still something you will need to handle ( eg. not all SA's are relevant without a BA or an EA released in the past ). - KB
