+    my ($server, $isupdate, $impotent) = @_;
+
+    # Replace if this script does an update for ip/domain.
+    return 0
+	if ($isupdate);
+
+    #
+    # Initialize server IP/MAC sitevars (for ARP lockdown).
+    #
+    Phase "updatesitevars", "Initializing ARP sitevars", sub {
+	if (ExecQuiet("$SUDO $UPDATESITEVARS")) {
