You will get this warning with 2.0-beta11 and earlier, as the
--persist-tun code has some issues when being used with --pull.

For example, suppose that --persist-tun has been specified, but on restart 
the server (via --pull) wants to give the client a new IP address? 
There's a potential conflict here.

In beta12 and later, the --persist-tun code on the client is smarter and
will only persist the state of the currently open TUN/TAP interface on
restart if the new pull from the server produces an identical
configuration.

To help encourage the server not to change the configuration of a client 
which connects multiple times, beta12 and higher on the server has the 
--ifconfig-pool-persist option as well.
