I used NixOS for a couple of years. My experience is like this:
- It is a rolling release (mostly)
- You write a declarative configuration for your system, e.g., my config will say I want Neovim with certain plugins, and I can also include my Neovim configuration
- It is stable, and when it breaks it is easy to go back
- Packages are mostly bleeding edge
Yes absolutely. It is really great. It is also a source of frustration, e.g., missing configuration options, non-obvious options and so on. Overall it works well.
