Build Legacy-Free OS Images
A fancy wrapper around dnf --installroot, debootstrap, pacstrap and zypper that may generate disk images with a number of bells and whistles. Generated images are "legacy-free". This means only GPT disk labels (and no MBR disk labels) are supported, and only systemd based images may be generated. Moreover, for bootable images only EFI systems are supported (not plain MBR/BIOS).
