So, basically, it is like an FS-snapshots which runs in its own chroot or a VM, while one could "atomically" replace one "snapshot" with another, and there should be some kind of "volume manager", because we do not want to replace the data. It looks like "windows way" - instead of solving dll-hell problem we would make "images" and restore them when a system is crashed. But this will not solve dependency-hell problem, because it is about standardized, well-defined, stable interfaces (like BSDs or Plan9 are trying to maintain), not file systems or VMs.
