[one-users] Using CloudInit for contextualization

[Wilma Hermann]

Hi,

I'm using the release image from yesterday (02-Feb-2014 03:39) [1]. And the
machine uses cloud-init 0.7.3:

# virt-cat one-42 /var/log/cloud-init.log | grep running
2014-02-03 15:18:56,873 - util.py[DEBUG]: Cloud-init v. 0.7.3 running
'init-local' at Mon, 03 Feb 2014 15:18:56 +0000. Up 4.48 seconds.

[1]: http://cloud-images.ubuntu.com/releases/13.10/release/

Thanks in advance
Wilma
