Overview

Presenter for per-node /etc/hosts content.

/etc/hosts is raw text — pvectl does not attempt to parse it. In table mode only summary metadata is shown (node, line count, digest). JSON/YAML output exposes the raw ‘data` string. Describe output prints the full content under a “Content” key.
