-As far as I understand it, from CentOS 7.3 and on OHPC/Warewulf switch to GPT disk UEFI boot loader. This involves a boot manager (efibootmgr) that looks not at a master boot record (MBR) on a bootable partition but insteads looks at a file (grubx64.efi). To boot UEFI environment variables need to be supported and you do that in BIOS.  Read the OpenHPC thread "Stateful provisioning with warewulf does not work (ohpc 1.3.5)". You also need to add these packages
+As far as I understand it, from CentOS 7.3 and higher versions, OHPC/Warewulf switch to GPT disk UEFI boot loader.

-My hardware is an ASUS esc4000fdr G2 bought in 2013. In the BIOS boot CSM menus I can set boot filter options to "UEFi and Legacy" and for each type (PXE, Storage,...) I set "UEFI first". These setting allow the CentOS7.2 image to still Legacy PXE boot. Nice.

-But the CentOS 7.5 image...not. No matter what settings I use to boot UEFI I continue to receive EFI variables not supported. If I boot the 7.5 image Legacy wise I receive a "can find path to tmpfs error" in mkbootable. The owner of the list thread posted this solution. Look in the deploy script on how to handle that.
+But if I build a CentOS 7.5 image...not. No matter what settings I use to boot UEFI I continue to receive "EFI variables not supported" in the adhoc-postscript step. If I boot the 7.5 image via Legacy boot I receive a "can not find path to tmpfs error" in the mkbootable step.
+The owner of the list thread posted this solution for the UEFI problem. Look in the deploy script on how to handle that.  My work around was to deploy a 7.2 image using a Warewulf stand alone 3.6.99 installation, then update the node kernel. (building a 3.6.99 version [[cluster:139|Warewulf Stateless]]).
