The dracut initqueue may quit immediately and won't trigger any hook if there is no "finished" hook still pending (finished hook will be deleted once it return 0). This issue start to appear with latest dracut, latest dracut use network-manager to configure the network, network-manager module only install "settled" hook, and we didn't install any other hook. So NFS/SSH dump will fail. iSCSI dump works because dracut iscsi module will install a "finished" hook to detect if the iscsi target is up. So for NFS/SSH we keep initqueue running until the host successfully get a valid IP address, which means the network is ready.
