I just like to comment that its a very long winded process and It would be better if it would be done right up front in the initial server setup process instead of after.
Also Im not to sure about the update process and what affect that will have on the system. ie is it going to be OK to do a normal apt-get update in the future and what happens when there is a dist update not to mention updating ispconfig and that everytime we will have go in and manualy adjust several files.
It all seems to add to the complexity of running and maintaining the system.
