Why everyone is switching to NixOS ?

Hi everyone!

I saw that NixOS is getting popularity recently. I really have no idea why and how this OS works. Can you guys help me understanding all of this ?

Thanks !

People love Nix because of the OS configuration based around a single config file. Essentially, you define your system configuration in this file, including installed programs, then you rebuild your system based on that configuration.

The beauty here is that you can easily move this file to another machine running NixOS and reproduce your configuration there. You can also roll back changes by simply rebooting and choosing the last known good build and you're back in business.
