This info is used for starting subsequent domains not the xenstore
domain itself so I think it will.
Whichever process starts the xenstore stubdom watis for it to initialise
and then writes the necessary parameters to xenstore. Future toolstack
invocations can then read it back. The toolstack doesn't need to know
where the xenstore is running since it just uses /proc/xen/xenbus.
