Title:
/etc/init/network-interface.conf uses ifconfig, should use "ip"
instead since ifconfig is deprecated..
Status in One Hundred Papercuts:
Triaged
Status in ifupdown package in Ubuntu:
Triaged
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.
