The cosmos generator linked a consumer to its provider only through an '<role>' in group_names reference or an explicit provides: name. A hard dependency has neither -- pinning the provider on unconditionally is exactly what removes the Jinja reference the generator was reading -- so web-svc-asset's bond to web-svc-file vanished from the diagram the moment it became binding. Match a service key against the provider's own primary key from the registry, in both directions. Services the role turns off drew a solid 1:1 edge, claiming a mandatory relationship for something that carries nothing at deploy time. They now render as a red 0..0 edge; edge merging gained a real precedence so a provider consumed through two keys stays live when only one is off. Named colour, not hex: a '#' opens an entity code in the mermaid lexer and turns the whole diagram into a parse error on GitHub. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

# Sudo
|
|
|
|
## Description
|
|
|
|
This role installs the [sudo](https://en.wikipedia.org/wiki/Sudo) package and deploys a default sudoers file to ensure secure and consistent privilege escalation on the target system. It uses a preconfigured sudoers file that follows best practices and includes directives to read drop-in files from `/etc/sudoers.d`.
|
|
|
|
## Overview
|
|
|
|
Optimized for security and ease of administration, this role guarantees that sudo is installed and configured according to recommended practices. The provided sudoers file includes essential comments, host/user aliases, and defaults to help prevent misconfigurations.
|
|
|
|
## Cosmos
|
|
|
|
The diagram places Sudo in the Infinito.Nexus cosmos: the components it deploys (capabilities), the central services it consumes (dependencies), and its outward reach (federation and bridged external networks).

Solid `1:1` edges are fixed relationships; dashed `0..1` edges are conditional (enabled only in matching deployments); red `0..0` edges are turned off in this role. Node markers show the role's deploy modes (💻 host, 🐳 compose, 🐝 swarm); ❌ marks a service that is explicitly turned off, and ⚙️ an Ansible role dependency declared in `meta/main.yml`.
|
|
|
|
## Purpose
|
|
|
|
The primary purpose of this role is to ensure that the target system has a reliable sudo configuration. By installing the [sudo](https://en.wikipedia.org/wiki/Sudo) package and deploying a standard sudoers file, the role facilitates proper administrative access and minimizes potential security risks.
|
|
|
|
## Features
|
|
|
|
- **Sudo Package Installation:** Installs the [sudo](https://en.wikipedia.org/wiki/Sudo) package if it is not already present.
|
|
- **Default Sudoers Configuration:** Deploys a default sudoers file with best-practice settings.
|
|
- **Drop-in Inclusion:** Ensures that configuration files from `/etc/sudoers.d` are included.
|
|
- **Security Focus:** Provides commented guidelines to avoid common sudo misconfigurations.
