If you set TEMPORARY_STATE=yes, files and folders from rwtab are in
tmpfs so it doesn't really matter if it is cleanly unmounted or not,
it will be lost anyway - important is that it doesn't hang.
If you need persistence for this stateless setup, you can set
persistent storage partition, STATE_MOUNT in
/etc/sysconfig/readonly-root.
See again ovirt-node for an example how is this used.
