       <para>For non-Linux systems, there is currently stub
-      implementation provided. As DHCP servers need to know available
-      addresses, there is a simple mechanism implemented to provide
-      that information. User is expected to create interfaces.txt
-      file. Format of this file is simple. It contains list of
-      interfaces along with available address on each interface. This
-      mechanism is temporary and is going to be removed as soon as
-      interface detection becomes available on non-Linux
-      systems. Here is an example of the interfaces.txt file:
-      <screen>
-# For DHCPv6, please specify link-local address (starts with fe80::)
-# If in doubt, check output of 'ifconfig -a' command.
-eth0 fe80::21e:8cff:fe9b:7349

-# For DHCPv4, please use following format:
-#eth0 192.0.2.5</screen>

+      implementation provided. Interface manager detects loopback
+      interfaces only as their name (lo or lo0) can be easily predicted.
+      Please contact BIND10 development team if you are interested
+      in running DHCP components on systems other than Linux.</para>
