It is a system with several servers (various platforms/distros). One piece of software runs on all of the servers. For it to operate correctly, the instance on one server (prime) must start before the others (auxiliary). So a boot delay is added (via a script sourced from initscript, which first waits for network to come up) to set the boot delay values for each server - prime at 0, others at some other value of 15 to 110 seconds depending on platform. But when it is necessary to manipulate the service interactively via the "service" command, the boot delay needs to be bypassed.
