uefi booting

[rmkraus]

Enable UEFI for PXE booting and RHCOS.... I guess 😢

[rmkraus]

UEFI PXE Booting:

• [x] install grub image

  
  yum install grub2-efi-x64.x86_64
  mkdir /var/lib/tftpboot/uefi/
  chmod 0755 /var/lib/tftpboot/uefi
  cp /boot/efi/EFI/BOOT/BOOTX64.EFI /var/lib/tftpboot/uefi/
  cp /boot/efi/EFI/redhat/grubx64.efi /var/lib/tftpboot/uefi/
  chmod 0644 /var/lib/tftpboot/*

 -  [x] configure dhcpd.conf
