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>

# Package Manager Installation
|
|
|
|
## Description
|
|
|
|
This Ansible role installs [Kevin's Package Manager](https://github.com/kevinveenbirkenbach/package-manager) and updates packages using `pkgmgr` on Arch Linux systems. It provides a unified interface for package installation and update management, ensuring consistent deployment across environments.
|
|
|
|
## Overview
|
|
|
|
The role abstracts package management operations using `pkgmgr`. It ensures the package manager itself is updated once per run and provides idempotent installation and update routines for specified packages.
|
|
|
|
## Cosmos
|
|
|
|
The diagram places Package Manager Installation 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 purpose of this role is to automate the installation and update process for Infinito.Nexus-related applications or other managed packages using `pkgmgr`. It simplifies package handling and enforces best practices for package deployment in automated environments.
|
|
|
|
## Features
|
|
|
|
- **Automatic pkgmgr Update:** Ensures the package manager is always up-to-date.
|
|
- **Idempotent Package Installation:** Only installs packages when necessary.
|
|
- **Flexible Notification:** Supports handler notification for post-install actions (e.g., Docker Compose builds).
|
|
- **Optional Privilege Escalation:** Controlled via the `pkgmgr_become` variable (default: `true`).
|
|
|

## Role Variables

|
|
| `package_name` | Name of the package to install/update | (required) |
|
