Intro

This is *MY* setup, and how I use sbuild, git-buildpackage and so on. Feel free to re-use, as I wrote it to share with others, however, this is in no way a source of truth.

Install needed packages

apt-get install sbuild devscripts git-buildpackage quilt openstack-pkg-tools

Tweak build software options

Setup sbuild

sbuild-createchroot --include=eatmydata,ccache bullseye /var/lib/sbuild/bullseye http://mirror.infomaniak.com/debian
