Pieman is a script for creating custom OS images for single-board computers such as Raspberry Pi. The images are based on Alpine and Debian-based distributions such as Devuan, Raspbian and Ubuntu. The authors of Pieman were inspired by the project named rpi23-gen-image. The main reason why it was decided to create a new project instead of improving the existing one is that rpi23-gen-image is intended for creating images only for Raspberry Pi 2 and 3 based on Debian GNU/Linux. Unfortunately, it doesn't have a way to be extended to support different operating systems and single-board computers. Improving the situation would require significant efforts to rework the codebase of the project. First, get the latest Pieman Docker image from Docker Hub.
