I was just trying to get openvpn working on my TW WSL image and it failed on
the fact that the group nobody is missing. I've checked and user nobody is
missing as well.

lkocman@DESKTOP-DESO8KI:/etc/openvpn> sudo openvpn --config heroes.conf.UDP

lkocman@DESKTOP-DESO8KI:/etc/openvpn> groupadd nobody

I think we should add it to make it more convenient for users so they can get
most of it. 

Workaround:
lkocman@DESKTOP-DESO8KI:/etc/openvpn> sudo groupadd -g 65534 nobody
lkocman@DESKTOP-DESO8KI:/etc/openvpn> sudo useradd -s /bin/false -G nobody -u
65534 nobody

This applies to both TW and Leap images.
