 We're mostly concentrated on programmatically enforcing interface/device boot order to accommodate [TripleO](https://docs.openstack.org/tripleo-docs/latest/) based [OpenStack](https://www.openstack.org/) and [OpenShift](https://www.openshift.com/) deployments while simultaneously allowing easy management and provisioning of those same systems via [The Foreman](https://theforeman.org/).  Badfish can be useful as a general standalone, unified vendor IPMI/OOB tool however as support for more vendors is added.
