This page defines primary user-roles in using OpenEmbedded. The material resulted from some discussions at OEDEM that were truncated due to time restrictions.
The goal of identifying user-roles is to be able to categorize different tooling scenarios, and what types of users will be interested in specific features.
The application developer's main concern is developing and testing any given application on a target system. This person does not care nor want to learn much about the internal details of the build system or package metadata. The best possible case is that these systems are transparent and the developer is able to easily build and deploy applications to the target device.
Distro developer's concern is to compose packages and configurations into a working system. The disto developer has deep knowledge of packages available in Linux, and how sets of packages work well together. Additionally the distro developer is not afraid to work deeply within the build system to make it better, and to produce better, more maintainable package metadata and target systems.
