A System V init daemon script for Iguana

A System V init daemon script for Iguana

Rob Ayer of Benchmark Revenue Management, one of our customers, kindly donated this script for Iguana. We have not tried using it in production ourselves, but provide it as a resource to any Linux customers we have.

It generally makes sense under Linux to run Iguana:

  1. Under a specific user ID rather than root. This is better for security.
  2. Make sure the $HOME environment variable is set for that user account since the source code control system Iguana uses will not function without this variable being set.
