Comment # 9 on bug 985798 from Fabien Crespel

Same issue as Bj�rn Voigt here: I have OpenVPN enabled at startup, without a
private key password, but since this changed was applied my system hangs at
startup waiting for a passphrase. It took me a while to even understand it was
OpenVPN doing this...

Since there seems to be a better option by adding askpass to the config file,
could you please revert the systemd service change?
