Boring systems are reliable systems

Clear logs, small configuration files, and a tested restart procedure solve more problems than another layer of automation. The best maintenance window is often the one you never need.

Keep defaults understandable

A useful default should be easy to explain and easy to change. Configuration belongs in one place, generated files should be reproducible, and secrets should never become part of the source tree.
