        Proposed changes to ncm-filesystems (and a future ncm-stab)
        A few months ago, Ian requested some things that make perfect sense about ncm-filesystems. I more or less have the time to implement it now, so here it goes: 1) "preserve" and "format" don't make sense anymore. They do for the installer, but not on a live system. So, the component should just ignore them. It should remove a FS if it disappears from the profile, and create it if it appears. Great care should be taken so that nothing gets removed by mistake, so check your "protected_mounts" field!!! 2) Sometimes all users need is to modify the fstab for some devices that aren't handled by this component. Say, tmpfs, SMB mounts.... according to Ian's proposal, fstab manipulation should be MOVED to a different component, namely ncm-fstab. 3) As a consequence, ncm-filesystems will depend on ncm-fstab. 4) There will be NO modifications to the current schemas for block devices and filesystems. Maybe some relaxation of the checks, to cover more FSs and pseudos. In any case, it will all be backwards-compatible.

        Security by default: The importance of lean systems
        There are a few very well-known security prinicples in information security such as security by default, security in depth. However, in reality we have seen that people very often overlook some simple but important details, which might eventually lead to a system being compromised. This presentation will give a few examples and observations that we have seen in our day to day operation and try to explore the ways of how Quattor can help improve or enhance security.

        Quattor Software Process
        Building the components of the Quattor toolkit, packaging those components, and testing them are all essential for maintaining Quattor as a high-quality fabric management system. The current tools and processes are not effective. This presentation provides the plan for moving to a new set of build tools and services to better support the Quattor software development and release process.

        BEgrid Quattor installation current state and help required from community
        BEgrid (Belgian GRID) is using Quattor in a non standard way. A central server handle configurations for all the sites. Each site is running a "Quattor client" retrieving and compiling the configurations. There is no push to site. The central machine is becoming old and the hardware start failing. A fresh installation is required and it's the opportunity to refresh everything a use Quattor in the standard way. The task is not so easy and we have a lack of experience (at least at BELNET). So, we would like to present the situation and where we want to go. We expect inputs from the Quattor community to help us having a clean situation.

        Future changes in QWG Nagios templates
        Nikhef's templates for configuring Nagios contain some enhancements compared to the standard QWG templates. During this presentation the differences will be discussed. Based on that, the future development of the Nagios templates can be discussed.
