+2. maas: region: interface: default mode DHCP
+
+Switch MaaS interface mode default from AUTO to DHCP.
+This way, MaaS will not statically assign IPs *outside* the dynamic
+reserved range, but instead DHCP will assign them *inside* the range.
+
+One alternative would be to handle this via API calls, for each
+node's PXE physical interface, but that overcomplicates things.
