NixOS is honestly so beautiful and rare. I'm delighted that the project is moving forward in this way.
A friend of mine called it a "rabbit hole" but TBH it's words of power -- I can speak new instances of my environment into existence, not only on newly-acquired compute devices, but on other OSes as well (I put some effort into segmenting the user environment and system config between home-manager and standard /etc/nixos/*)
Nix flakes will only make me more powerful
