-An example of a time we'd want to use this is when a package from CentOS 7.3 has a bugfix we want to test on CentOS 7.2.  The RPM can be downloaded from the CentOS 7.3 repo, placed in the CentOS 7 lab-extras repo and installed.  Example: http://tracker.ceph.com/issues/18094

+===== Installing the package =====
+Since ceph-cm-ansible makes sure the lab-extras repo is present on all testnodes, a quick way to update a single package on all testnodes would be to run an ansible playbook.  Here's an example from when nfs-utils was done.
+<code>
+## ansible-playbook thisplaybook.yml --limit="smithi*,mira*"
+- hosts:
+    - testnodes
+  become: true
+  tasks:
+  - name: Upgrade nfs-utils to lab-extras version
+    yum:
+      name: nfs-utils
+      state: latest
+    when: ansible_distribution == 'CentOS'
+</code>
+This updated the version to nfs-utils-1.3.0-0.**35**.el7.x86_64.  You can make sure no hosts got left behind by running ''ansible -a "rpm -qa nfs-utils" mira | grep -B 1 nfs-utils-1.3.0-0.33.el7.x86_64''.
