+# OpenVPN automatically creates an /etc/resolv.conf (or sends it to
+# resolvconf) if given DNS information by the OpenVPN server.
+# Set PEER_DNS="no" to stop this.
+PEER_DNS="yes"
+
+# OpenVPN can run in many modes. Most people will want the init script
+# to automatically detect the mode and try and apply a good default
+# configuration and setup scripts. However, there are cases where the
+# OpenVPN configuration looks like a client, but it's really a peer or
+# something else. DETECT_CLIENT controls this behaviour.
+DETECT_CLIENT="yes"
+
+# If DETECT_CLIENT is no and you have your own scripts to re-enter the openvpn
+# init script (ie, it first becomes "inactive" and the script then starts the
+# script again to make it "started") then you can state this below.
+# In other words, unless you understand service dependencies and are a
+# competent shell scripter, don't set this.
