+Policy for a baremetaluser role
+===============================
+
+When deploying Slurm on baremetal nodes, it is typical to select a specific
+baremetal node, and give it the expected hostname. We allow this via a tweak to
+Nova policy.
+
+Similarly, it is common that the IP address has to match the expected one for
+the given node. We tweak neutron policy to allow fixed IPs, even when we do
+not own the network.
+
+We should never use the admin role to do these operations, as it has far too
+much privilege.
