IRILL - Research and Innovation on Free Software Debian is the basis for a number of other software distributions. This BoF provides a space for representatives from derivatives and Debian to share experiences, find out what is working well or not working well and to discuss needs. We will also discuss Debian's derivative-related initiatives: front desk, DEX, census and guidelines. We will begin with introductions, move on to open discussion and finish with a short discussion of Debian's derivatives related initiatives.
