[ale] Remove systemd network handling

[DJ-Pfulio]

Which distro?

Many have deprecated and haven't used /etc/network/interfaces in a few years. This is a separate issue from systemd.

Any systemd service can be disabled, then "mask"ed to prevent it from running.
$ sudo systemctl list-units
will show the .services you can do that with.  Getting the wrong services can make for a bad day.
