You are right i just put it there because its being relevant to the 
whole geoip things. Givign it a default value will not really help much 
because i'am not printing it later on it just is necessay to poitn to an 
existing geopip file in plcace.

If it fails to be assinged then i will just cat /etc/err/out and see 
that it erred out and then take action to fix it.
