resolved watches networkd state changes and RTNL updates separately. RTNL is currently processed at SD_EVENT_PRIORITY_IMPORTANT, while networkd state changes are processed later at SD_EVENT_PRIORITY_IMPORTANT+5. If both are pending, an RTM_NEWADDR update can make a link relevant for LLMNR/mDNS scope allocation before resolved has consumed the corresponding networkd state update. This can let scope recalculation use stale per-link settings until the networkd event is processed. Run the networkd monitor source before RTNL by using SD_EVENT_PRIORITY_IMPORTANT-5. This lets resolved consume current link settings before reacting to RTNL address updates in the same event loop iteration. Fixes #42079 Co-developed-by: OpenAI Codex <noreply@openai.com>
