I wanted Debian packages of the master branch's HEAD, so, of course, I automated it: https://github.com/markuslindenberg/docker-freeswitch-debbuilder

The repository contains a Dockerfile (for creating a Docker image) that will, when run, do everything that's necessary and output packages.

Background: I wanted to explore use cases for Docker and I really need the packages. And I'm really tired of the manual process.
