When a nomad client restarts/upgraded, nomad restores state from running task and starts the sync loop. If sync loop runs early, it may deregister services from Consul prematurely even when Consul has the running service as healthy. This is not ideal, as re-registering the service means potentially waiting a whole service health check interval before declaring the service healthy. We attempt to mitigate this by introducing an initialization probation period. During this time, we only deregister services and checks that were explicitly deregistered, and leave unrecognized ones alone. This serves as a grace period for restoring to complete, or for operators to restore should they recognize they restored with the wrong nomad data directory.
