[ale] Network Connection - Lack Thereof

[DJ-Pfulio]

Thought /etc/udev didn't exist anymore. Systemd took over that.
I modified grub conf to always force the wired NIC to be eth0. Life has
been easier since on single NIC machines. Google will find the steps.

For multi-NIC machines, I use the F*&^%ng systemd names.  Another
problem systemd tried to fix that I didn't have.  More unwanted
complexity to help 2% of the users.

(That's been true for a while now, but many systems have fairly repeatable boot sequences.)  Note that you can still make the board-level rules available as a fallback.
