[Bug 850166] [NEW] ifquery does not respect mappings

[Clint Byrum]

Public bug reported:

Given this interfaces file:

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0

mapping eth0
  script /map

iface FOO inet dhcp

auto eth1
iface eth1 inet dhcp

And the script /map is just

#!/bin/sh
echo FOO


I would expect ifquery --list to show:

lo
eth1
eth0

But instead it shows

lo
ignoring unknown interface eth0=eth0
eth1
