As long as its NFS server and its local mknod use the same mapping, I
don't see the problem.  (Unless it uses NFSv2, in which case I think
the local mknod and the NFS client on the diskless machine would have
to match; the server is documented as doing v3, though I haven't
actually snooped the wire to be certain that's what it's using.)

Have I missed something?  That would certainly be possible.
