This converts a "classic" distro to any image based OS with ComposeFS support!
Arch was chosen as the base as it's pretty easy to install and comes with systemd-boot pre-configured.
This is NOT what you might know as a "rebase". This is a full in-place re-install, you data and users will be lost.
This is mainly usefull for custom images that don't have ISOs, for exemple Bootcrew or FreeDesktop-based bootc images like ProjectBluefin's Egg.
