Yes, there is that.  I never figured out exactly how it works,
but I do remember that even a different OS version would do it.
One of my first NFS server configurations included booting between
two different versions of HP-UX.  The hardware configuration was
the same, other than the root partition.  It knew the difference.

Still, I will guess that if you really need to build a server
such that the disk can be replaced and continue, that it is 
possible to do it.  There is a reason they make hot-swap disks.
