News from the EDOS project: improving the maintenance of free software distributions

The EDOS research project aims at contributing to the quality assur- ance of free software distributions. This is a major technical and engineering challenge, due to the size and complexity of these distributions (tens of thou- sands of software packages). We present here some of the challenges that we have tackled so far, and some of the advanced tools that are already available to the community as an outcome of the first year of work.
