In reality that is also true for upstream support as well ... see the first line in any upstream update in the solutions section. Here is an example: https://rhn.redhat.com/errata/RHSA-2014-1870.html First line in Solution Section: Before applying this update, make sure all previously released errata relevant to your system have been applied. That does not say pick and choose errata or only install security errata. In reality, one should only NOT install an update if that update causes problems. That is any Errata update, not just security updates. The reason, all updates are built on a staged system. Any updates built today are built on / linked against the updates from yesterday. If you use a perl package (that is an example name, could be any package) built against today's update set on 6.3 .. it may or may not work at all, or work correctly. It also could possibly introduce security issues never tested for because that combination is unique to your install. I might work fine, it might be horrible. signature.asc Description: OpenPGP digital signature ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Although the state of the thing itself is not very helpful :( My intention was to automatically get warned, when there are pending security updates. I therefore reworked the yum plugin of Munin [1] But as I see now, this will not work for CentOS as long as the data (a working updateinfo.xml) is not existent in the repos.. I will add a note in the Munin yum plugin to inform other CentOS users about this #fail. It would be good to add such a hint also in the CentOS package of the yum-plugin-security. Until now there is no info about the no-op nor in the man page neither under /usr/share/doc. Shall I create a bug report addressing the missing doc? Or will it get answered with won't fix as the fix would need to fork an own CentOS version of the plugin, so no longer simply copy the package from upstream (rh) # rpm -ql yum-plugin-security /etc/yum/pluginconf.d/security.conf /usr/lib/yum-plugins/security.py /usr/lib/yum-plugins/security.pyc /usr/lib/yum-plugins/security.pyo /usr/share/doc/yum-plugin-security-1.1.30 /usr/share/doc/yum-plugin-security-1.1.30/COPYING /usr/share/man/man8/yum-security.8.gz Cheers, Gabriele [1] https://github.com/munin-monitoring/munin/commits/devel/plugins/node.d.linux/yum.in ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] yum-plugin-security
We have an alert for CentOS packages with security updates, and I was
curious how it works. Turns out that what it does is do a search
engine search for
[$package $version site:https://rhn.redhat.com/errata/]
{yeah, doesn't even put $version in quotes!}
And then fetches the top result looking for the string /Security Advisory/
We update all packages to tip whenever we update. This
not-completely-accurate method turns the ordinary you have some
updates, to the occasional you have security updates! zomg!
Amusing. Keeps people awake.
Anyway, if we did have such a tool, we should definitely build it such
that the only thing it does is look at your current machine and say,
you're not at tip, and some of your packages have security
problems. update to tip. That would not increase the size of the
tree nor encourage people to unsafely do partial updates. And it
wouldn't require a huge historical analysis.

so far and thanks for your replies to all contributors in this thread,
Gabriele
