Support for software configuration is gaining importance. Large modern reusable software such as platforms or product lines often have a vast number of configuration settings that need to be specified in order to derive a running system. Examples of highly configurable systems include the Linux kernel, Eclipse, and eCos. They are supported by configuration tools, respectively, Linux Kconfig, Eclipse Yoxos, and eCos configuration tool. We have been studying the configuration models of these systems in a related project on "Feature Models in the Wild".

The aim of this project is to understand what problems the users face during configuration and provide corresponding support in the configuration tool. Our current focus is to understand and support conflict-resolution in Linux Kconfig and eCos configurator.

In our newest progress, we have introduced priorities to guide the error fixing process. The corresponding paper has been submitted for review, and a technical report has been published. If you are a reviewer of our paper, please see our technical report page for the pseduo code and the experiment results.
