Detached tasks spawned on every config generation set and restored the placeholder DNS without ordering, so a set could back up the placeholder itself and a later restore reported success while leaving it in place. Reconcile from the applied config under the lifecycle lock, and restore whenever the core stops. Keep one backup per network service, never back up the placeholder, and restore only while the service still holds it. Scripts verify every read and write and are killed after 5 s. Refs #8070, #8168
