Comment 3 for bug 1785757

The base OS is deployed by server manager and is a minimal version.

This is the base OS used for reimage

root@nodej2:~# server-manager show image --image_id ubuntu-16.04.2.minimal -d
{
    "image": [
        {
            "category": "image",
            "id": "ubuntu-16.04.2.minimal",
            "parameters": {
                "kickseed": "/var/www/html/contrail/images/ubuntu-16.04.2.minimal.seed",
                "kickstart": "/var/www/html/contrail/images/ubuntu-16.04.2.minimal.ks"
            },
            "path": "/cs-shared/images/ubuntu-16.04.2-server-amd64.iso",
            "type": "ubuntu",
            "version": "ubuntu-16.04.2"
        }
    ]
}
