Yeah, btrfs is awesome and it’s easy to use with NixOS as well. The rollback mechanics are different in that Nix isn’t actually rolling back it’s just rebuilding a previous revision (commit) of the config.

If the audio is out of sync in your files you can use ffmpeg to fix them.

I’ve been using NixOS for over a year and I can’t imagine using anything else. I originally started using it because I liked the idea of version controlling the entire configuration, but now I use it for everything.

The most underrated feature of Nix is being able to instantly roll back an update that breaks something that you don’t want to deal with. An update breaks kitty or neovim? If I have something to do I can just roll back and fix it later. Awesome.

It’s not for everyone. I can’t imagine someone who isn’t at least a hobbyist programmer having the desire to overcome the technical nature of it.

Heres my config.

You can install Nix on arch to try it out without changing your OS.
