- download the .deb package from OpenBuildService and add it to config/packages.chroot/
- the package will be auto-upgraded when it is added to Debian repositories https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=754129
- we could also add the OpenBuildServie repository to sources.list but that would mean trusting a third-party repository, which we might not want
- in the future we should verify package integrity/authenticity with GPG signatures (#56)
