What is the stability and maintenance loop like for each There are not so may packages that needs to be installed on client side (about 10) but in conclusion you will get functionalities like remote-commands through osad and monitoring. The package upgrades could be handled with errata and update management easily. > component ?

Config management should be extended and there are already some good ideas out there, like depending remote commands. Best Regards Marcus > PS: Your email client is broken.
