Bug Description

As the summary says
/etc/init/network-interface.conf uses ifconfig but it should use "ip" instead:

This is the line:
ifconfig lo 127.0.0.1 up || true
It probably should be:
ip link set dev lo up || true

This command fails on a clean minimal ubuntu install since net-tools that provides ifconfig isn't installed.

There should be no need to set ip while bringing the interface up (which could interfere with future ipv4-only or ipv6-only setups) as the kernel configures it automatically.

It's a non-ideal default configuration.
