Specifically in this case a Node WWN for fibre channel fabrics that does
not depend upon an assigned WWN in any particular Fibre Channel card
(multipathing might make it desirable to have a synthetic Node WWN that
can also be passed to partner systems in a failover configuration).
More generally a system unique identifier available early (pre mountroot)
could be useful for a number of things. Why're you asking?
