Creates a gpt table partition
makes 2 partition e.g /dev/sdc1 /dev/sdc2.
Format the /dev/sdc2 partition
mkfs.ext4 -L aufs-rw /dev/sdc2
burn the ISO into the first partition
# sudo dd bs=4M if=obarun-2022.03.12-x86_64.iso of=/dev/sdc1 status=progress oflag=sync
Mount the second partition as cow_device at boot time.
doesn't work at all :/
