(The tun0 somehow survived some openvpn experimentation I was
doing last night. I have no idea what that IP is. It survived my
Jessie -> Stretch upgrade done this afternoon.)
Or do you generally have no networking until X starts and gives you
NetworkManager, etc?
No. I didn't mean to imply that the X failure was at all
connected to my networking puzzles. I like to boot to a CLI and
then type "startx". I don't even know where to go to find
NetworkManager. Absolute systemd noobie here.
Thank you
