Dear guix, My interface should be configured to have 2 static ip addresses, an IPv4 address and a global IPv6 address. The static-networking-service-type will only accept one per device, and will reject the IPv6 address (if I drop the IPv4 address) because it can't parse it. My workaround is to add a shepherd service that runs ip address add dev eno1 the-address and ip address delete dev eno1 the-address, with ip from iproute2. Maybe static-networking-service-type could do something better for me? Best regards, divoplade
