title: 'Uninstall avahi Server Package'

description: |-
    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.

rationale: |-
    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.
