Comment 5 for bug 1148016

Hi Gavin,

This is important because the root.tar.gz images used by the FPI are stored in the Cluster Controllers, since they are currently generated based on the ephemeral images.

Now, since each node on an FPI installation process is being told where to obtain the root.tar.gz image from, it is important to determine the nodegroup/cluster controller the node belongs to. By doing so, we ensure that the node contacts the correct Cluster Controller (which is the one the node it booted from) in order to be able to successfully obtain the image.

The proposed way to do this is via the cluster_host variable made available for the preseeds.

Unfortunately, there's no easy way to work around this.

Cheers.
