Bug#592550: Provide support for SSH-Key authentication (Supports Eucalyptus and Amazon EC2)

[Kyle Moffett <Kyle.D.Moffett@boeing.com>]

Package: network-console
Severity: wishlist

When performing partially-automated virtual-server installations (using
services such as Eucalyptus or Amazon EC2, for example), it's not really
practical or secure to use password-based authentication for the
installer.

Furthermore, such virtual server environments provide an automatic
method of provisioning public SSH keys during the installation process
via an HTTP URL.

The Ubuntu guys seem to have a patch for this that never got merged:
  https://bugs.launchpad.net/ubuntu/+source/network-console/+bug/184108

For example, access to the following URL from an Amazon EC2 instance
will retrieve the SSH public key assigned during instance creation.
With the Ubuntu patch above I can just directly preseed this URL:
  http://169.254.169.254/2010-06-15//meta-data/public-keys/0/openssh-key

Cheers,
