The READMEs are generated from the role declarations. Six role READMEs gain
svc-net-tor in their dependency graph and the top-level table gains the Tor
Onion Service column entries, following cd1f07a91. The remaining lines are
template output: the author name becomes a link, two mermaid linkStyle rows,
and a reworded setup sentence in web-svc-mirror.
Left unregenerated the documentation would disagree with the meta/services.yml
it is derived from.
The generator was not re-run here: this is the output that was already in the
tree, checked to match the committed declarations.

# NSS
|
|
|
|
## Description
|
|
|
|
This Ansible role guarantees that a target resolves the `*.localhost` names it serves, without going through DNS.
|
|
|
|
## Overview
|
|
|
|
A deployment that keeps the shipped `DOMAIN_PRIMARY` serves names under `infinito.localhost`. Those exist in no zone, so a task that reaches the deployment's own domain from the host depends on the `myhostname` NSS module, which maps any `*.localhost` name to loopback per RFC 6761.
|
|
|
|
- Installs the module where it is packaged separately (Debian family) and no-ops where it ships inside systemd (Arch, RedHat)
|
|
- Appends `myhostname` to the `hosts:` line of `/etc/nsswitch.conf`, idempotently
|
|
- Runs once per play
|
|
|
|
## Cosmos
|
|
|
|
The diagram places NSS 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).

end

```
|
|
|
|
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`.
|
|
|
|
## Features
|
|
|
|
- **Distro-agnostic:** the package list is empty on families that ship the module with systemd
|
|
- **Idempotent:** both tasks are no-ops once the module is present
|
|
- **Narrow:** it configures name resolution and nothing else, so callers that only need resolution do not also change the system hostname
