Seems like this distro is getting a lot of traction recently. Has anyone tried it? Is it any good?

      Your whole system is defined in a file called configuration.nix. This file describes everything about your system: all packages installed, which Desktop Environment / Window Manager to use, and also configuration for almost everything (e.g. zsh or neovim). When “switching” (which is basically installing/updating the system), Nix looks at the configuration and changes your system according to what you’ve declared in the configuration.nix, installing or uninstalling packages for instance.

      So, the state of your system is “declared” in a single file, which can be tracked in git or backed up wherever. If you have mulitple systems, you can also share parts of your config between them, which makes configuring and customizing stuff a lot easier.

      There are a lot of other aspects, but thats the basic gist of it

        Is it a big learning curve? Is this the emacs equivalent of OS configuration/installation?

        edit: another question - Could I play around with it by installing in qemu and if I like that, take my configuration.nix from qemu and install it as my main OS?

          I’d say it’s a pretty steep curve unfortunately, and nixOS is also not perfect, mind you

          • The nix language (that is used for the configuration) itself has sometimes weird syntax. It’s also a proper functional programming languages with all bells ans whistles that brings
          • The documentation is less than ideal (to put it mildley). Most of the times you need to search reddit (rip) and the forums to find how to do certain things.
          • Nix is not FHS compliant. Basically everything is a symlink to some file in the nix store, located in /nix. Packages installed with nix are patched to work that way, but things not installed with it might not run out of the box

          As for trying it out, yeah copying the config from the vm should work (except for maybe some hardware-specific stuff). remember to backup your stuff just in case lol

        That sounds really cool… so you could just take that file, do a clean install of nix, then put that file back and it’ll install all your old packages and stuff?

          Not just your packages, but all your config as well.

          Also, I believe updates are transactional, so if something goes wrong in the middle it can just abort and your system isn’t left in an inconsistant state. And if an update breaks something you can easily roll back to a previous version.

      Oh my bad. Yeah you can configure almost anything in a declarative way on the /etc/nixos/configuration.nix file:

      services.xserver.enable = true;
      services.xserver.displayManager.gdm.enable = true;
      

      Or

      services.xserver = {
        enable = true;
        display manager.gdm.enable = true;
      };
      

      You can define a lot more (programs, users) and then you build the config file to take effect. By default NixOS is immutable so you can’t change anything in the root partition and if there is something that broke you can rollback to a previous build!
