Notes

Create partitions

dd if=/dev/zero of=heyo-1 bs=2097152 count=1024

# Creat 256MB EFI partition.
parted heyo-1 mkpart primary fat32 2048s 501760s
parted heyo-1 set 1 boot on

# Create remaining partition.

New way with guestfish:

#### sparse heyo-1 10G    # Create a new sparse 10G disk.

disk-create heyo.img raw 10G preallocation:sparse
add heyo.img
run                  # This "activates" the disk and creates /dev/sda.

# Create the GPT label.
part-init /dev/sda gpt

# Add partition 1.
part-add /dev/sda primary 2048 501760
part-set-bootable /dev/sda 1 true
mkfs vfat /dev/sda1 label:EFI

# Add partition 2.
part-add /dev/sda primary 501761 20971486
mkfs ext4 /dev/sda2 label:ROOT
