Hi Maxim, Thanks for the hints. I am using static network configuration via dhcpcd. I literally plagiarised the config snippet from `info guix` to configure it. I am also not using GNOME, so no NetworkManager involved. If you take a look at the config I provided in my original post above, you will see that I set the DNS in the wg configuration AND in dhcpcd-service-type, so I tried to get rid of the latter and reconfigure, to no avail.
Thus, apparently, you've found the culprit: dhcpcd not honouring the way resolvconf now expects to find that particular line in /etc/resolv.conf !
