From 637e5faaa0af9b897a8d20c6dbb7ac670842b092 Mon Sep 17 00:00:00 2001 From: Viacheslav Hletenko Date: Wed, 1 May 2024 13:36:14 +0000 Subject: T6056: Change static-host-mapping shold not restart snmpd We have several config XML definitions that use the same python3 script `system_host-name.py` https://github.com/vyos/vyos-1x/blob/current/interface-definitions/system_name-server.xml.in https://github.com/vyos/vyos-1x/blob/current/interface-definitions/system_host-name.xml.in https://github.com/vyos/vyos-1x/blob/current/interface-definitions/system_static-host-mapping.xml.in https://github.com/vyos/vyos-1x/blob/current/interface-definitions/system_domain-name.xml.in https://github.com/vyos/vyos-1x/blob/current/interface-definitions/system_domain-search.xml.in Any change in these scripts calls to restart the `service snmpd` The service `snmpd` should be restarted only if `host-name` or `domain-name` was changed. It is a good idea to rewrite it to `get_config_dict` in the future.
