Gate on $facts['elasticsearch']['memory_lock'] so existing nodes without the fact are unaffected. When enabled: - Set bootstrap.memory_lock: true in elasticsearch.yml - Add systemd override with LimitMEMLOCK=infinity - Set vm.swappiness=1 via sysctl Disable oracular builds - the repo is unused and deprecated.
