paved road
also: supported path, best practice
A stable, well-maintained, and officially supported approach or workflow in Linux development and deployment; the intended or recommended way to accomplish a task.
A "paved road" in Linux culture refers to the documented, tested, and officially blessed way of doing something in a system or project. It contrasts with ad-hoc or unsupported workarounds that may be fragile or undocumented.
For example, installing software via your distribution's package manager (apt, dnf, pacman) is a "paved road"—it's tested, verified, and maintains system consistency. Installing binaries directly from the internet is an "unpaved road" that bypasses these safeguards.
The metaphor emphasizes that following established practices leads to predictable results, easier maintenance, and better integration with the rest of your system. Administrators and developers are encouraged to stay on the paved road for production systems.
