NixOS in my laptop

I've installed NixOS in my laptop -a Thinkpad x280- for my very first time, and the installation process was pretty straightforward.

NixOS Installation Guide

Everything is working as expected after some tweaking: X11, power management, acpi -including the backlight-, the touchpad, suspend, audio, camera and all of my applications are working fine with the (almost) same configuration as I had in my previous Arch Linux system.

After a week working with NixOS, still is "a stranger" distro to me because there are something "weird things" like non-standard directories (and everything is "packed") in the /nix path and there are some "concepts" around the configuration, which can be splited into more files and also some concepts like flakes and home-manager configurations, which makes sense to me if you want to perform post configurations into your dotfiles and declare all the custom parameters for your tool chain.

NixOS is like a sort of ansible/chef tools integrated with the operating system and this is a very cool concept.

This is an experiment anyway, I'm still learning a lots of new concepts and it's is a long way to run. Still, I'm thinking on try another desktop installation but with Wayland and with the sway echosystem. Also I want to tweak again the configuration in order to perform a new installation but with encrypted filesystems and start using my Yubikey, but that's another history...

This is my current running configuration.nix file (use at your own risk!):
