LocalSetup
This page describes how to set up proposed-migration on a clean system.
Installability checks and autopkgtests
In the simplest case you just want to reproduce the "first stage" of britney2-ubuntu, which checks that -proposed packages were built on all expected architectures, are installable by themselves, issue autopkgtests, collect their test results, and produce a production-like excuses.html and excuses.yaml.
TODO..
Full Ubuntu production setup
The full Ubuntu production setup is done by britney1-ubuntu. This creates the archive index lists, per-series configuration files, calls the first and second stages of britney2-ubuntu, and issues the actual copying of packages from -proposed to -release. It assumes having a local mirror and a helper script promote-to-release which does the actual copying.
TODO: Fully document and/or provide charm for this.
