From da7f1292838f087e2179705f2778f78ddd85cba8 Mon Sep 17 00:00:00 2001
From: "Daniel F. Dickinson" <dfdpublic@wildtechgarden.ca>
Date: Wed, 17 Dec 2025 18:28:37 -0500
Subject: [PATCH] zabbix_agentd: Tweak config file for OpenWrt
Note: original patch had no header, header added 2025-12-16, while
bumping package version. Modified 2025-12-25. Modified 2026-01-21.
1. Use syslog not a file for logging
2. Place PidFile under /var/run/zabbix
3. Only start passive agent by default
4. Do not do active checks by default
5. Use the system hostname as hostname (except on zabbix server)
6. Include configurations under /etc/zabbix_agentd.conf.d/
7. Drop privileges to the zabbix-agent user (instead of zabbix)
