Even if there are no dependency loops, a missing init script can cause 
serious problems if you don't catch it right away - particularly if the 
person who was originally responsible for installing said service is no 
longer working with you. (Of course, this is at least as much a problem 
of organization as it is technology: you should have access to 
documentation - or at least human expertise - on all of the pieces of 
your production system, and doubly so for the custom ones.)
