To build an UEFI capable image,
1. Two partitions are created with GPT partition table. First partition
contains the root file system, while the second partition is an EFI
System Partition(ESP). ``parted`` is used for creating partitions.
2. As part of installing grub boot loader, the ESP is mounted
to /boot/efi directory of the root file system so that grub will
install required grubx64.efi and other dependent packages on ESP.
3. Grub configuration files are modified to work with respective
distributions.
