Le problème vient d’un signal non émit par le script if-up.d/upstart :

Ce script envoi un signal qui est intercepté par /etc/init/failsafe.conf, tant que le signal n’est pas envoyé, ce dernier bloque avec les messages indiqués :

En ajoutant des logs on voit que l’alias sur eth0 n’est pas prise en compte par les ubunturies alors que tout est bien monté:

Aucun problème en supprimant l’alias eth0:0 de /etc/network/interfaces, l’alias eth1:0 ne pose pas de problème.

Je ne reproduit pas le problème sur un eolebase avec le /etc/network/interface de l’amon problématique.
