Engineering Team, which is subscribed to cloud-init. https://bugs.launchpad.net/bugs/1564911 Title: Network interfaces file name is not accepted by ifup Status in cloud-init: Won't Fix Bug description: The change introduced in 1189 ( https://bazaar.launchpad.net/~cloud- init-dev/cloud-init/trunk/revision/1189#cloudinit/distros/debian.py ) breaks ifup at least on trusty because ifup only reads files in /etc/network/interfaces.d that match ^[a-zA-Z0-9_-]+$. Changing the filename fixed the problem for me.
