By default, zabbix rpms are only allowed to be installed at default path. It follows the basic Linux file system standard. But for certain customers, the zabbix assets are preferred to be installed in customized directory.
So we add Prefix option in zabbix.spec file and some steps in post & postun phases to enable the relocate option during the rpm installation. The spec file modification is based on 3.0.19 version. And hope this could be added as a default config since no harm to logic.
