True, I think it's more a more elegant setup than the ZFS version. Why actively rollback to a snapshot when ephemeral memory will do that automatically on reboot.

That said I'll just mention that ZFS support on NixOS is like nothing else I've seen in Linux. ZFS is like a first-class citizen on NixOS, painless to configure and usually just works like any other filesystem.
