startup script change proposal

[richlv]

with agent startup scripts, provided by zabbix, agent fails to start if pid file is there - even if no actual process is running.

so, i'd like to porpose copyig misc/init.d/suse/9.3/zabbix_agentd to misc/init.d/suse/10/zabbix_agentd and improve it there.

given that the script already handles the situation when pidfile exists, but the process is not running (by using checkproc), a very simple patch follows to allows zabbix_agentd startup even if system was not gracefully shutdown :

+                   ;;
        esac

        startproc -p ${ZABBIX_PID} -u zabbix ${ZABBIX_BIN}

such a situation probably could be handled in zabbix_agentd itself, but this change is trivial and fast to apply.

the problem also might be relevant for other startup scripts, but i don't want to mess up all of them
