Moins,

just for clarification:



"network NFS DHCP boot fails on multiple NIC machine"
https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/182940

"initramfs-tools: Network configuration can't work with multiple
interfaces"
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=467078

Regards,
