Every time my kernel is upgraded by pacman (the `linux` package) openvpn is no longer able to connect with this error message:
sudo openvpn my-config-file
ERROR: Cannot open TUN/TAP dev /dev/net/tun: No such device (errno=19)

It works again after reboot. It should work even without reboot.

I have found a forum thread on this topic as well .
This task depends upon

 FS#16702  the updated kernel package does not supply a compatible version of the tun kernel module so it can not be loaded after the old kernel has been removed.
You can avoid the issue by ensuring all required modules are loaded before kernel update or only performing kernel updates when you are able to power cycle the system.
