CentOS 6/7 EFI Kickstart

The only difference for EFI based systems in a kickstart file is the addition of a /boot/efi partition.

It is placed in the “Physical Partitions” section after the /boot partition.

# Physical Partitions #
part /boot --fstype="ext4" --ondisk=sda --size=512
part /boot/efi --fstype="efi" --ondisk=sda --size=512 --fsoptions="umask=0077,shortname=winnt"
part pv.01 --fstype="lvmpv" --ondisk=sda --grow --size=18512
