From 502248599bfc0b36daf0f8dd83bee5bc6e1b24e4 Mon Sep 17 00:00:00 2001

Subject: 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.
Tweaked further 2026-07-16.
1. Use syslog not a file for logging.
2. Place PidFile under /var/run/zabbix-agent.
3. Only start 1 passive agent by default.
4. Do not do active checks by default.
5. Use the system hostname as hostname.
6. If started as root, drop privileges to the zabbix-agent user, not
a shared (with server and proxy) zabbix user or root, per upstream
recommendation:
https://www.zabbix.com/documentation/7.0/en/manual/installation/install#security-recommendation
7. Include configuration files under /etc/zabbix_agentd.conf.d/.
8. Require configurations under /etc/zabbix_agentd.conf.d/ end in .conf.
(other files are ignored for configuration purposes).
