Appreciate the response. Yeah Im in the same boat. May be time to say goodbye to AutoDeploy. Then again, with 8U1's host profile changes to json & clusters switching to desired state config, it may actually be more stable. Will be interested to see when it gets released.
As far as the HTTP UEFI-- I think Im good now. I battled with our Bluecat DHCP for a while until I realized I didnt even need to bother as our HPE gear could do it natively w/o any DHCP customization by simply adding the mboot.efi url as an HTTP Boot Option in the profile. Works like a charm.
How (if you know) are folks getting kickstart customizations done if they have secureboot enabled? Looks like nothing in %firstboot will run with secureboot.
Thanks again,
