A little consideration before starting $EDITOR will not hurt. In order to write a well-tempered rc.d script for a system service, we should be able to answer the following questions first:
Is the service mandatory or optional?
Will the script serve a single program, e.g., a daemon, or perform more complex actions?
Which other services will our service depend on, and vice versa?
From the examples that follow we will see why it is important to know the answers to these questions.
