Comment 1 for bug 1630519

should only support one situation. The choice is bad.

> "I want to make changes to nova.conf on *api nodes only*. I put changes in /etc/kolla/config/nova/nova-api.conf but they're ending up on compute nodes"

the configure should be only copied to the node who need it, this is a bug[0].

the custom config file also support ansible template and this should be documented. like

cat <<EOF > /etc/kolla/config/nova.conf
{% if service_name='nova-api' %}
[DEFAULT]
debug=True
{% endif %}
