Comment 1 for bug 1053190

I've just added a package named 'cloud-initramfs-dyn-netconf' to the cloud-initramfs-tools package.
We'll utilize this package to fix this bug in the following manner.
 * add cloud-initramfs-dyn-netconf to the ephemeral images
 * modify the build of the ephemeral images so that /etc/network/interfaces is a symlink to /run/network/dynamic-interfaces
 * open-iscsi initramfs package run 'configure_networking' which will cause some device to be configured
 * cloud-initramfs-dyn-netconf's will then write /run/network/dynamic-interfaces with the configured interface name ('eth0') as 'auto' and 'dhcp'.
