+
+I desire the following options in `/etc/resolv.conf`:
+
+.. code-block:: bash
+
+ rotate timeout:1 attempts:1
+
+Ubuntu or Debian
+----------------
+
+For Ubuntu or Debian based systems, place the options in
+`/etc/resolvconf/resolv.conf.d/base`:
+
+.. code-block:: bash
+
+ rotate timeout:1 attempts:1
+
+These options merge with the options from DHCP and end up in `/etc/resolv.conf`.
+
+Then restart the host, or at least networking.
+
+Redhat or Centos or Fedora
+--------------------------
+
+For Redhat, Centos or Fedora, add the following to `/etc/sysconfig/network`:
+
+.. code-block:: bash
+
+ RES_OPTIONS="rotate timeout:1 attempts:1"
+
+Then restart the host, or at least networking.
