Hello!

Trying to get this working in a container ubuntu/focal. When I first launch the container, I can list /dev/net/tun, so when I try to do mknod it says it exists.

But when I try to launch openvpn I always get

ERROR: Cannot open TUN/TAP dev /dev/net/tun: No such file or directory (errno=2)

I've tried debian and opensuse containers, same result. What am I doing wrong?
