Goal seems similar to Bedrock but implementation* differs. This one seems more desktop oriented, more stable (uses a a conventional approach of containerization of other distros), but also less flexible (Bedrock allows mix-and-matching even system packages). *It's basically Arch + distrobox which handles all the low-level work.
