[smokeping-users] Slave Graphs not updating on master

[Nick Toseland]

Hi Greg

I managed to fix the the issue by as you say giving www-data access to 
the RRD files.

The problem is I don't want to have to do this for every RRD file that 
is created.

Do you happen to have the link to the messages  for mod'ing the startup 
script?

Thanks for your help

NIck
