Quando eu inicializo (ou reinicio a rede, como mostrado abaixo) no meu sistema Debian, ele tenta obter uma concessão de DHCP na minha interface de rede que está desconectada, como você verá abaixo; infelizmente, atrasa a inicialização em cerca de um minuto. 

root@**HOSTNAME**:~# cat /etc/network/interfaces 
# 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
allow-hotplug eth0
iface eth0 inet dhcp

auto wlan0
iface wlan0 inet dhcp
    wpa-ssid **THE-NETWORK-NAME**
    wpa-psk **THE-PASSPHRASE**
root@**HOSTNAME**:~# /etc/init.d/networking restart
[warn] Running /etc/init.d/networking restart is deprecated because it may not re-enable some interfaces ... (warning).

Eu provavelmente estou negligenciando algo realmente óbvio, mas agora estou perplexo. Alguma idéia?

você está especificando eth0 como um dispositivo auto e um allow-hotplug : 

auto eth0
allow-hotplug eth0

isso é contraditório, esp. o dispositivo auto não verificará se o dispositivo está realmente conectado .

, então você deve remover a linha com auto eth0 .
