Abstract: Disclosed are systems and methods that include user interfaces (“UIs”) and a controller for automating the building, management, and distribution of operation systems (“OSes”) with different customizations for different users. A UI may include selectable elements for different OS distributions, and may present a first set of components from a selected particular OS distribution and a second set of components that are not included with the particular OS distribution. The controller may generate a custom OS build based on a first subset of components that are selected from the first set of components, and a second subset of components that are selected from the second set of component using the UI. The controller may provide a repository that is accessed with an identifier and that links to each selected component of the custom OS build, and may distribute the custom OS build from the repository to a node.
