Abstract
In Operating system hardware reconfiguration: A case study for Linux, it was determined through experimentation that a Linux-based C2 operating system can successfully undergo a hardware migration and operating system hardware reconfiguration. The direct benefit of this is the ability to forgo any new operating system reinstallation in order to support newer hardware by using mechanisms internal to the operating system that support changes in hardware; this results in a decreased waiting time for system reaccredidation and redeployment. Since an operating system can evolve over time, it can accommodate changes in the system’s hardware, thus presenting a tangible advantage for the Navy as this allows the operating system to be maintained over the long-term. However, there are complexities involved when maintaining an operating system for long periods. Therefore, this report serves as an introduction and a simple methodology for performing system maintenance-related tasks that include upgrading, updating, as well as data backups and restoration. This report is neither all-inclusive nor a replacement for qualified system administrators with years of experience. Instead, it can be used as a useful source of information to provide recommended practices, procedures, and information to help in planning for long-term system maintenance.
