In reply to nc.

You are correct, AFAIK, yum update --security will have no effect on Centos Base and Update repos as it lacks the metadata needed… EPEL works on Centos and the repo has the metadata to support this.

Without trying the command listed in the article, I’m not sure if the commands listed in the article will install all updates or only 3rd party repos that support this on Centos, but regardless it’s misleading. It would work on RHEL, however.

Do the CentOS 7 repos provide the metadata required to support the yum --security usage? I read elsewhere that they do not (and that it's a feature only available to the repos used by RH subscribers) and that as a result, these updates are essentially a no-op on CentOS7.

The conservative approach when applying updates is to perform a system reboot, especially for security updates and indeed kernel updates. Yes, indeed a reboot is vital.

What about if the security update requires a system reboot to take effect. And if there any new kernel update available is that going to get updated automatically with this configuration. Thanks
