Abstract: Embodiments disclosed herein are related to systems and methods for updating an operating system image. A system includes a processor and a system memory. A customization module receives end user defined customization parameters for an updatable base operating system image. The customization module further translates the received customization parameters into image state transition steps. The state transition steps cause the implementation of the customization parameters when applied to the updatable base operating system image. A generation module generates the updatable base operating system image by applying some of the image state transition steps. An update module updates the generated updatable base operating system image without the need for further end user input by applying some of the state transition steps to generate an updated operating system image.
