Hrm, weird. Anyway:

I don’t quite think so…

Oh? For me, this worked until extremely recently.

Fun fact:

$ sudo modprobe tun
$ sudo /etc/init.d/openvpn start

This seems to work. So I think the module may not be autoloaded
correctly any more. Maybe the kernel? My last boot was on 2nd of
July, therefore almost certainly with linux 3.14.9-1 whereas now
I run:

Linux tglase.lan.tarent.de 3.14-1-amd64 #1 SMP Debian 3.14.12-1 (2014-07-11) i686 GNU/Linux

Adrian, you’re welcome for me filing the bug ☺
