Hi, The current version of Imagefactory [1] running with CentOS build system (CBS) is few versions behind upstream releases of Imagefactory [1] . Imagefactory recently added a new feature to build HyperV variant of Vagrant image and also has capability to build Vagrant box for VMware Fusion. I am confident that bringing these features to CBS will help the community in general. In case you are not aware about Imagefactory [1] , CBS uses it to do Vagrant box builds for CentOS and other projects e.g. Atomic Developer Bundle (ADB) in Atomic SIG. I am wondering how we can facilitate a process to bring upstream features of Imagefactory to CBS. One suggestion from Ian was that we should create a cbs-test setup similar to production CBS setup and use it to build confidence around the new features of Imagefactory and then move the feature to production. If you have better ideas you should speak now :) [1] https://github.com/redhat-imaging/imagefactory Thanks, Lala
