zabbix pid file (ubuntu 7.10)

[marcelein]

i installed zabbix with

apt-get install zabbix-server-mysql zabbix-frontend-php zabbix-agent

on my ubuntu machine, it works
when is reboot my system the bootlog says it has been startet when i do a

ps aux | grep zabbix

there is nothing
i try to start it manualy and got no errors but nothing is startet when i check my processes again
so i created a directory for my pid files (server and agent) with

mkdir /var/run/zabbix-agent
mkdir /var/run/zabbix-server

then i chown that to my zabbix user and zabbix starts
now i reboot again and this directorys are gone how can it be?
does i have to change those dirs to some home directory or do those steps in my init script?
does anybody got a less dirty solution?
why are those directorys not automatically created and kept with the installation?

That doesnt work for me too

I changed the /var/run/zabbix* to /opt/run/zabbix* in conf files as said in some post here.
Added permission for zabbix to each folder.
then after no probs are there.
