Preventing Wheel Reinvention: The psgconf System Configuration Framework
Mark D. Roth, University of Illinois at Urbana-Champaign
Most existing Unix system configuration tools are designed
monolithically. Each tool stores configuration data in its own way,
has its own mechanism for enforcing policy, has a fixed repertoire of
actions that can be performed to modify the system, and provides a
specific strategy for configuration management. As a result, most
tools are useful only in environments that very closely match the
environment for which the tool was designed. This inflexibility
results in a great deal of duplication of effort in the system
In this paper, I present a new architecture for system
configuration tools using a modular design. I explain how this
architecture allows a single tool to use different strategies for
configuration management, enforce different ideas of policy, and
prevent duplication of effort. I also describe the implementation of
this architecture at my site and identify some areas for future
