One way to improve the performance of Ansible is through fact caching. Rather than gather facts in every play, we can configure Ansible to cache them in a persistent store. An example Ansible configuration for doing this is as follows: [defaults] gathering = smart fact_caching = jsonfile fact_caching_connection = ./facts fact_caching_timeout = 86400 While this mostly just works, there are a few places where we unconditionally gather facts using the setup module. This change modifies these to only gather facts when necessary. We no longer execute the MichaelRigart.interfaces role using become: true, since it may gather facts and we do not want it to do so as root. The role uses become where necessary.
