Mine is: Ubuntu LTS boxes, Debian, Fedora, and — the interesting one — XCP-ng hypervisors. The goal is simple: one control node, a handful of playbooks, and the ability to answer two questions at any time: <em>what updates are pending?</em> and <em>are these hosts fully patched?</em></p> <p>This post builds the whole system from zero. Every file and command is copy-pasteable. The hostnames and IPs below are made up — swap in your own. At the end there&rsquo;s a list of the quirks that actually cost me debugging time, so you can skip my detours.</p>
