@Tom Matthews: Are you sure that https://bugs.launchpad.net/netplan/+bug/1759014/comments/62 is netplan's fault? On my test box the systemd renderer DHCP settings end up in the same stanza for IPv4 and IPv6, like
[DHCP] RouteMetric=3333 UseMTU=true UseRoutes=false UseDNS=false
netplan even complains in case of differences: "ERROR: ens4: networkd requires that use-dns has the same value in both dhcp4_overrides and dhcp6_overrides".
Looks like it's systemd not honoring that value for IPv6 as expected, doesn't it?
