The "ip link set multicast ..." command corresponds to the the IFF_MULTICAST flag hence to the #:multicast-on parameter. > Anyhow, I suggest adding a =E2=80=98multicast?=E2=80=99 field to , with > #t as its default value, and honoring this. I'm not sure is the right place for this flag. If there are two records in the same list, one for ipv4 and one for ipv6 it means that we need to repeat this flag twice. Same for the MTU, having different MTU for ipv4 and ipv6 addresses doesn't have any meaning. The MTU and multicast properties belong to the device itself. I think we should introduce a record that would gather the properties that can be passed to the "link-set" method of Guile-Netlink. The record would point to a unique . We would remove the device field from . Then each service would provision (concat 'networking- (network-device-name device)) or something like that, to fix https://issues.guix.gnu.org/52511 as well. How does that sounds?

What we could do then, is expose the record as a direct equivalent of the Guile-Netlink record. The links list of the record would contain all the links that are managed by Guix. We would require all "device" fields that appear in the records to have their matching link declared. If the link doesn't already exists (vlan, veth type) then link-add is called, otherwise nothing happens. The link existence can be tested using link-name->index. link-set would always be called afterwards to setup link properties. static-networking-shepherd-service would then create on service per link present in the links list. The provisioned name would be (concat 'networking- (network-link-name link)). On tear down, which is equivalent to "herd stop networking-", we would call link-del if the link was created by Guix with link-add, or (link-set ... #:down #t) if the link was already present. I'm not sure how to distinguish between those two cases at this step. This sounds like a complex plan, that will moreover require and adaptation of existing static-networking configurations, but I cannot think of anything easier to fix this issue and the other one I reported.

Hmm yeah. I think it=E2=80=99s good to have defaults right, so #:up and #:multicast-on set. We could set those when a device lacks a corresponding link. Food for thought=E2=80=A6 Ludo=E2=80=99.
