Overview

Zypper is a wrapper class around the zypper package manager

Zypper offers access to the system-wide zypper environment, but it also allows for running zypper in an isolated environment using ‘Zypper.isolated’. That way Machinery can safely add repositories and download packages without polluting the host.
