Comment 2 for bug 1672604

Confirmed - from an AIO inventory right now:

    "compute-infra_containers": {
        "children": [
            "aio1-host_containers"
        ],
        "hosts": []
    },
...
    "memcaching_containers": {
        "children": [],
        "hosts": []
    },
...

I think the reason behind this may be related to: in the user_config.yml (or conf.d/x.yml files) you will have:
"compute-infra_hosts".

Whereas - in the AIO you do not have "memcaching_hosts"

==========

What is the desired outcome though? I agree the inventory generation around env.d/x.yml files is horrible but I'm not sure how it should look in regards to this bug.
