    package: base-files: turn error into warning
    
    Some users have their routers configured to supply a DHCP range that
    includes the local interface address.
    That worked with dnsmasq because it automatically skips the local
    address.
    
    Re-enable those existing configurations for the release and hint at
    possible future problems.
