Package: systemd-resolved,isc-dhcp-client Hi,
When systemd-resolved started replacing and providing resolvconf, things looked good, but isc-dhcp-client no longer propagates DNS servers to resolved. This used to work when resolvconf and systemd-resolved were coinstallable and one used resolvectl to implement resolvconf. The crux is that resolvconf contains the integration scripts that make isc-dhcp-client run resolvconf even when resolvconf is provided by systemd-resolved. Now that systemd-resolved conflicts with resolvconf, it broke that integration, which is bad. I briefly talked to Michael about this and he figured that we wouldn't want to go through the extra resolvconf layer and rather do things directly. Indeed, this is what has happened for ifupdown already. ifupdown now contains /etc/network/if-*.d/resolved and integrates directly. NetworkManager does it directly likewise. isc-dhcp-client should likely do it as well. Thus I think a good solution to this bug would be: * isc-dhcp-client ships scripts to directly integrate with resolved. * systemd-resolved Breaks isc-dhcp-client in versions that don't integrate. * resolvconf no longer participates in propagating DNS servers from isc-dhcp-client to systemd-resolved. Neither on the interface level nor on the package level. Does that make sense? Workaround: One can manually place the previous resolvconf script from https://sources.debian.org/src/resolvconf/1.91%2Bnmu1/etc/dhcp/dhclient-enter-hooks.d/resolvconf/ Helmut
