The update is failing because, for some reason, the record does not 
exist. This has nothing to do with the script, unless it is because the 
script never created it in the first place, but then surely there would 
be something in the logs about this.

As I said, the script is run with the output of DHCP, this can succeed 
or fail, but it would be logged, at the same time, dhcp does its thing 
and this usually works. The script can fail, but dhcp work, the only 
thing that connects them is that dhcp runs the script with the required 
arguments (or not)
