Uninstall avahi-autoipd Server Package


If the system does not need to have an Avahi server which implements the DNS Service Discovery and Multicast DNS protocols, the avahi-autoipd and avahi packages can be uninstalled.


Automatic discovery of network services is not normally required for system functionality. It is recommended to remove this package to reduce the potential attack surface.
