[11:36] <Odd_Bloke> cbolt: Yeah, you'll want to configure the list of datasources that cloud-init uses; have a look in /etc/cloud/cloud.cfg for the default list, and override it by dropping an extra config snippet in a file in /etc/cloud/cloud.cfg.d/.
[11:37] <Odd_Bloke> cbolt: Alternatively, if you're using the Ubuntu (and, I assume, Debian) packaging, `dpkg-reconfigure cloud-init` should prompt you to select the ones you want.
