I have never understood the full connection(s) between SystemImager, SystemInstaller, System Configurator, and SISuite. What are they?
The SystemImager and LUI (Linux Utility for cluster Installation) projects entered into a collaboration in 2001. SystemImager was to be the foundational component, with SystemInstaller and System Configurator being implemented to achieve the specific goals of LUI that were not yet present in SystemImager. The goal of SystemInstaller (created by Michael Chase-Salerno) was the ability to install a SystemImager image directly to an imageserver, bypassing the need for a golden client. The goal of System Configurator (created by Sean Dague) was to achieve distribution independence with regard to, well, system configuration details implemented by SystemImager such as network and boot loader settings. It was determined that the three of these packages should take on a common identity as the System Installation Suite.
