Deploy
When you deploy, one thing you want to do is verify that you haven't made live edits that you forgot about and will clobber. This is easy to do. Compare the public directories in conf v. the .deploy locations:
diff -rq /opt/conf-meza/public/ /opt/.deploy-meza/public/
LocalSettings.php should either be compared to the copy in /etc/etckeeper.mirror.d or the jinja template in the mediawiki role.
