I am very glad to hear this =) That would be these changes: * Set UseDomains to true, by default, on Ubuntu. On Ubuntu, fallback DNS servers are disabled, therefore we do not leak queries to a preset 3rd party by default. In resolved, dnssec is also disabled by default, as too much of the internet is broken and using Ubuntu users to debug the internet is not very productive - most of the time the end-user cannot fix or know how to notify the site owners about the dnssec mistakes. Inherintally the DHCP acquired DNS servers are therefore trusted, and are free to spoof records. Not trusting DNS search domains, in such scenario, provides limited security or privacy benefits. From user point of view, this also appears to be a regression from previous Ubuntu releases which do trust DHCP acquired search domains by default. Therefore we are enabling UseDomains by default on Ubuntu. Users may override this setting in the .network files by specifying [DHCP|IPv6AcceptRA] UseDomains=no|route options. * resolved: create private stub resolve file for integration with resolvconf. The stub-resolve.conf file points at resolved stub resolver, but also lists the available search domains. This is required to correctly resolve domains without using resolve nss module. * Enable systemd-resolved by default * Create /etc/resolv.conf at postinst, pointing at the stub resolver. The stub resolver file is dynamically managed by systemd-resolved. It points at the stub resolver as the nameserver, however it also dynamically updates the search stanza, thus non-nss dns tools work correctly with unqualified names and correctly use the DHCP acquired search domains. * libnss-resolve: do not disable and stop systemd-resolved resolved is always used by default on ubuntu via stub resolver, therefore it should continue to operate without libnss-resolve module installed.
