Pure EFI boot, you can just have: part /boot/efi --fstype="efi" Plus whatever volumes (PVs etc.) that you want. Other question mark I'd have over the partitioning is that it's got a separate /usr. part /usr --fstype="xfs" --ondisk=sda --size=30000 --asprimary Separating off /usr from / is no longer supported AFAIK. jh
