Zabbix agent start-up problem

From MyWiki

For some reason after reboot zabbix_agentd didn't start on one of my servers. Turned out to be a missing check in start script of the agent and it was trying to create PID file in nonexistent directory:

zabbix_agentd [1583]: cannot create PID file [/var/run/zabbix/zabbix_agentd.pid]: [2] No such file or directory

Here is a patch to fix it:
