Comment 0 for bug 1756742

I have a fresh Bionic install with DI which doesn't mention netplan in ENI:

$ more interfaces
# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)
# Generated by debian-installer.

# The loopback interface
auto lo
iface lo inet loopback

This is particularly confusing since ifupdown is not installed :)

I think this file wants to say that netplan is installed by default, ifupdown is still available if needed, and where to go for more information.
