+# How This Works:
+# 1. /opt/iiab/iiab/iiab-install copies scripts/local_facts.fact to /etc/ansible/facts.d/local_facts.fact
+# 2. Ansible runs /etc/ansible/facts.d/local_facts.fact to identify the OS
+# 3. ./iiab-install (iiab-stages.yml) or ./runrole (run-one-role.yml) or Admin Console (iiab-from-console.yml) invoke the correct /opt/iiab/iiab/vars/<OS>.yml
