+    FreeBSD and pfSense installs must likewise leave the agent with a durable,
+    installer-owned rotating log. rc.d has no journal and `daemon(8)` discards
+    the child's stdout, so the rendered rc.d service must carry the agent's

    The shell installer must disclose `--enable-commands` as Pulse command

    Proxmox LXC Docker inventory as the operator-visible reasons to enable it.
