User-provisioned infrastructure::
For user-provisioned infrastructure clusters, you manage boot images as part of your infrastructure. To update the boot image, download the latest {op-system} image for your architecture from link:https://mirror.openshift.com/pub/openshift-v4/dependencies/rhcos/[mirror.openshift.com] and update your infrastructure to serve the new image.

For the full procedure, see "Adding compute machines to bare metal".

That table row was for UPI baremetal, and not the UPI generically, which could be any platform the user desires. That is why https://docs.redhat.com/en/documentation/openshift_container_platform/4.21/html/machine_management/managing-user-provisioned-infrastructure-manually has a section per platform

I was hoping to narrow down the link a bit. I recall clicking your link ^^ and feeling lost. If it is just UPI, can we link to "Adding compute machines to clusters with user-provisioned infrastructure manually"?

For the full procedure, see Adding compute machines to clusters with user-provisioned infrastructure manually for your platform.

Yes, we should. UPI is not a platform - it is a way for provisioning the cluster. The customer is free to mix and match any platform in UPI, assuming they configure it correctly
