bug#44571: Cannot configure a static IPv6 with static-networking-service-type

[divoplade]

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
