+# Example: install and configure vpn-router during first boot.
+#
+# This is one way to reach the state described in README.md, not an interface
+# the package depends on. It writes the configuration file directly, which
+# keeps everything in one place and works the same whether or not debconf is
+# involved.
+#
+# Template variables are Terraform templatefile() placeholders. Adapt or drop
+# them for whatever renders this file.
