Kali Rolling Repository

In contrast to dev-potassium, potassium-rolling is expected to be of better quality because it is managed by a tool that ensures the installation capability of all packages contained therein. This tool will select packages that are updated from the dev-command and copy them into potassium-rolling only if they have been verified to be installable.
