Latest commit 22c5381 Feb 24, 2017 @cron2 cron2 Fix '--dev null'
To test whether a server is reachable and all the key handling is
right, openvpn can connect with "--dev null --ifconfig-noexec" to
avoid needing to the client with elevated privileges.

This was erroring out for no good reason (because the "set environment
variables appropriately" code didn't know if this is a tun or tap
device...) - treat --dev null as "tap", done.
