Linux kernel development process currently consists of a few different main kernel branches and lots of different subsystemspecific kernel branches. This automates the process of installing and configuring the application, creating a repeatable process. Traditional approaches to softwaredevelopment methods tend to focus on supporting process engineers or quality engineers. It is an attempt to document how this community works in a way which is accessible to those who are not intimately familiar with linux kernel development or, indeed, free software development in general.
