Nixos: everything everywhere all at once
Good for you there wasn't an "ease of use" or "intuitive" field.
nixOS is for people who love config files
NixOS is for people who have accidentally uninstalled 90% of their system because they didn’t pay attention to what other packages depend on the thing they were uninstalling and were desperately looking for a an undo button.
I'm still a Linux noob all things considered, and I've been using NixOS for six months or more.
It is HARD, but I see the true value of it. I will never need to reinstall Linux because I broke it, that's simply impossible.
If I ever need to migrate my system, it's all backed up to github. With a single
every single .config file backed up, system upgraded, all packages updated.
I just love Nix, it's the perfect OS for me.
Now I just need to learn how to use flakes...
Sidebar: I've never asked before, but maybe someone can help me out. If I install a flake of an application, am I supposed to add it to the existing flake, or can I modulate flakes?
I've noticed when installing the nixvim flake it generates a new flake and it runs when I issue the
command, but I don't want to have to run that command every time. I feel like making a fish abbreviation isn't the correct way of doing this.
So I've only been using nix about a year and only used flakes. I use in two ways.
First, I have my main nix flake. Most everything is controlled from that. It has several outputs from full blown nixos builds per host or some home manager builds for non-nixos systems.
Third-party flakes I use as inputs to my own flake then use the override system to inject them into nixpkgs. Then I just install whatever like normal from nixpkgs. I can either override an existing pkg (neovim nightly replaces regular neovim for me), or you can just add as a new package to nixpkgs by using a different attribute name.
Second way is for projects with their own repo. I'll add a project flake that has a devshell with direnv so as soon as I enter that directory it sets up a sort of virtual environment just for that project. You can add outputs to it so others can use as a third-party flake.
My main starting point was https://github.com/Misterio77/nix-config for this design.
NixOS is from Max Verstappen country not Sebastian Vettel country
you don't even need to know where, you don't even need to know when. that's how every it gets
