zabbix: agentd pid file created even when not configured

[danielfdickinson]

Package Name

zabbix

Maintainer

@danielfdickinson

OpenWrt Version

SNAPSHOT

Also affects OpenWrt-25.12

OpenWrt Target/Subtarget

bcm27xx/bcm2712

Steps to Reproduce

1. Use default config from zabbix-agentd package
2. OR own config with no PidFile= configuration set

Actual Behaviour

With Zabbix 7.0.12 running zabbix_agentd in foreground mode would not create a PID file. With Zabbix 7.0.21 the same configuration running in foreground mode creates /tmp/zabbix_agentd.pid.

From the Zabbix code, creation of a pid_file in all cases appears to have been the intent, and previous behaviour was a bug.

It means, however the that the agentd config patch description and comment in the zabbix_agentd.conf for the zabbix_agentd.conf are now incorrect.

So this is a note to myself (as the Zabbix maintainer) to rework the pid_file configuration and update the patch comment.
