You can indeed achieve some reproducibility with Docker. It's tricky though, as you'd have to pin exact package versions of software. If you'd `FROM ubuntu:$VERION`, and would run an `apt-get update`, you're not guaranteed to get the same software. Nix is like ZFS, as that it breaks the wall between two previously distinct area's. Those being building software, and installing/configuration software on your OS. It's quite different from the snapshot-everything methodology that Docker uses. Yeah, one can split in multi-stage images etc, but than you'll be keeping track of which dependencies need to be moved between the stages yourself, in a manner that cannot be abstracted away, so you're doomed to repeat the same patterns over and over again. People also state that LVM + ext3 is more than sufficient compared to the complexity of ZFS. They miss out on the fact on how much more fine grained solutions are possible with ZFS. I've used niv [0] before flakes arrived, and am actually still using that instead of flakes. The experimental nature of them has scared me away from them, as I'm not daily involved in this ecosystem at the moment. [0] https://github.com/nmattia/niv#niv https://github.com/nmattia/niv#niv
