What are the benefits of NixOS's declarative configuration

The declarative configuration of NixOS offers several key benefits:

1. Reproducibility and Consistency:

   • NixOS ensures that the system configuration is consistent across different environments. This means that if a configuration works on one machine, it will work on another, reducing the "it works on my machine" problem.

   • Reproducibility is enhanced through the use of fixed-output derivations, ensuring that a specific configuration consistently produces the same result.

2. Simplified System Management:

   • All configurations are defined in a single file (configuration.nix), making it easy to manage and maintain systems. Changes can be tracked using version control systems like Git, facilitating collaborative configuration management and auditing.

   • This approach simplifies debugging and troubleshooting, as modifications can be easily reverted by
