If I wrote the script I would either have set it up to run regularly 
with a list of targets where it is needed and add new members to the 
list as appropriate or I'd add the setup to our stock images so it 
wouldn't be needed as a special case.  But in my experience, the kinds 
of things that need time consuming configuration aren't that predictable 
ahead of time.  What do you do when they relate to the switch where 
something is connected or something other than the group you've put the 
server in?
