RedHat created the 'yum-security' plugin for Yum, which is detailed here.
What is the status of 'yum-security' in CentOS 5.4 ?
When I last checked, 'yum-security' was still not supported by CentOS, according to this thread and http://bugs.centos.org/view.php?id=3578 . However, I have not been able to find much current information about this.
I read the Release Notes for CentOS 5.3 & 5.4, as well as the changelog for the yum-security RPM. Those are rather ambiguous. The post at http://lists.centos.org/pipermail/cento ... 16195.html suggests that this may be working soon.
Starting with 5.4, we will also have all fast-track rpms from upstream available in the fasttrack repository hosted at mirror.centos.org. This will start getting packages in the next few weeks, and also means that we will be able to move towards having a functional yum-security setup in place. Details on these will be posted by the 15th of Nov 2009.
However, I have not seen any updates about this functionality, although the details were to have been "posted by the 15th of Nov 2009".
Just checking in.
