+#!/bin/sh
+#
+# router.customize - configure router disk image for management by ansible
+#
+# This sets up a very basic image, just enough to allow ansible to log
+# in and become root with sudo. Also, bring up DHCP server on LAN
+# ports to allow access over ssh. All the rest of the configuration
+# happens via ansible.
