A. Please, check it here.
A. We plan to open our Spacewalk git branch during summer. We wanted to announce at the openSUSE Conference and we did not make it to have everything prepared.
Meanwhile, you can download it from http://beta.suse.com/private/uyuni-project/ (look into Media2 directories for the SRPMs).
A. We plan to release builds via the Open Build Service. Initially we will target openSUSE Leap 42.3 during summer, and openSUSE Leap 15.0 after that.
You can get an initial build at http://beta.suse.com/private/uyuni-project (you need to use the Media1 directories as repositories).
A. Yes. SUSE Manager is based on the Spacewalk project. As our branch diverged more and more, we decided to make the current SUSE Manager code-base the initial Uyuni, and we will base future SUSE Manager releases on Uyuni going forward.
A. While most of the bugfixes and enhancements from SUSE Manager were contributed back to Spacewalk, some features did not made their way back. To highlight some:
The server is a full Salt master and can manage systems running the Salt minion, with full configuration management support.
Building of image containers based on frozen channels.
Auditing of container images and Kubernetes clusters.
Initial configuration and setup based on YaST.
Infrastructure changes to keep the codebase modern (Java 8, Hibernate 5, React.js, Spark...)
