I've been curious about NixOS for quite some time. Reading about it I couldn't see how the config sharing capabilities, setup, or rollabck would be better than Arch and sharing the list of installed packages, using downgrade or chroot.
So I decided to run NixOS in a VM and I'm still confused. An advantage I can see for NixOS is its better use of cores and parallel processing for packages install.
It's clear that I'm missing something so please help me understand what it is.
Edit: Thank you to everyone in this great community! It's always so nice to have a constructive and sane discussion.
After reading so many comments, they all confirm what I've read before and I may realize that my real problem is already having a stable system and no need for the great NixOS options that are very neat but would not benefit my specific and simplistic needs.
That being said I can't refrain myself from being curious and will continue testing NixOS.
The need for only 2 config files is the top of the iceberg but hiding more complex configuration to rely on. Not that I really have too much spare time but I do enjoy learning and tweaking NixOS. With its current development state, things are changing a lot so it can keep me busy for months. That's probably what I was mostly looking for: another toy to play with.
Along my journey I will learn a lot about NixOS and may find a feature that will motivate my switch to it. Thanks again for all your precious feedback!
I'll also take this opportunity to share the best help I've found so far to start with NixOS: https://github.com/MatthiasBenaets/nixos-config And his 3 hours (!) video: https://m.youtube.com/watch?v=AGVXJ-TIv3Y
The problems with nix/nixos documentation are:
Also, the very top heavy decision making process harms the community. Some person with hundreds of commits can push through nearly any change (good or bad) relatively quickly, unless other frequent contributors are really really against it. However, fresher contributor with a great change is forced to go through a never-ending process and few stay to actually finalize it.
Pushing to
masterwas not seldom for a long time and IINM it isn't possible anymore. But maintainers can simply (and do) create a PR, make a change and merge it.These difficulties just make me want to fork nixos. For documentation, at least there's https://nixlang.wiki

Good points. If you go through the open pull requests on nixpkgs, there's a lot of stuff that never got through and it's not obvious as to why. I was happy to see a lot of stuff merged less than a week ago. But at this point, there's a huge backlog.
As to forking NixOS, which in my opinion means forking Nixpkgs, Guix system seems like a good start. I decided for NixOS because of proprietary packages as I use Steam, and support for secure boot which while still young and only through lanzaboote works very well for what I use it.
I'm glad they exist. It shows that the concepts can be successful using another language. To me, the major downside is exactly what you said: no proprietary stuff. Additionally, it's LISP.
In a fork, I'd try to change the way decisions are made, which software is used, add linting and autoformatting to repositories, move away from github (maybe by the time I find the time to we'll have federated sourceforges) and github actions, maybe use nickel or haskell instead of nix, generate documentation from sourcecode, try and use a distributed cache (tahoelafs, ipfs, storj or some other distributed/decentralised file storage), etc. Getting any of that done in the current repos seems like an uphill battle.

Let us know when you do! It's a huge undertaking and NixOS has a pretty big network effect. Doesn't mean no one should tackle creating an alternative. I fully believe declarative distros are the future for any production environment and that the space is far from taken by current distributions.
