Thanks - but it doesn't really give any more info that isn't elsewhere 
on the Web e.g. it doesn't give any clues on how to check if the trigger 
script is being run by the RPM containing the trigger script or by the 
triggering RPM

After several hours of installing, upgrading, removing, etc (in various 
combinations) test trigger and triggering RPMS, I think I've now got 
something that I can work with - it's a bit messy, but it will now work 
in a predictable fashion

Thanks
