 ##  Purpose
-Prior to the Driver Toolkit's existence, you could install kernel packages in a pod or build config on OpenShift using [entitled builds](https://www.openshift.com/blog/how-to-use-entitled-image-builds-to-build-drivercontainers-with-ubi-on-openshift "entitled builds") or by installing from the kernel RPMs in the hosts `machine-os-content`. The Driver Toolkit simplifies the process by removing the entitlement step, and avoids the privileged operation of accessing the machine-os-content in a pod. The Driver Toolkit can also be used by partners who have access to pre-released OpenShift versions to prebuild driver-containers for their hardware devices for future OpenShift releases.

 The Driver Toolkit is also used by the [Kernel Module Management (KMM)](https://github.com/rh-ecosystem-edge/kernel-module-management), which is currently available as a community Operator on OperatorHub. KMM supports out-of-tree and third-party kernel drivers and the support software for the underlying operating system. Users can create _modules_ for KMM to build and deploy a driver container, as well as support software like a device plug-in, or metrics. Modules can include a build config to build a driver container based on the Driver Toolkit, or KMM can deploy a prebuilt driver container.
