Lapis is a artifact build system made (primarily) for Yum/DNF Repositories inspired by COPR and Pungi. It is to be the official build system for Ultramarine Linux.
It is designed for easy configurability, and ease of contribution.
The Lapis backend is written in Python, and uses PostgreSQL for the database backend.
It uses standard Mock config files to configure the buildroots for each build, and createrepo
for full repo generation.
