I’ve been curious about NixOS for quite some time. Reading about it I couldn’t see how the config sharing capabilities, setup, or rollabck would be better than Arch and sharing the list of installed packages, using downgrade or chroot.
So I decided to run NixOS in a VM and I’m still confused. An advantage I can see for NixOS is its better use of cores and parallel processing for packages install.
It’s clear that I’m missing something so please help me understand what it is.
In short, Nix reduces the setup time, both for your system and for your projects. If you find yourself spending a while setting stuff up (for example, after a reinstall; or maybe you want to run your project on another PC and need to install the right dependencies), Nix will help. Otherwise, if your desktop is vanilla Fedora or whatever and you don’t do much programming (or you don’t have any dependency management problems), Nix probably isn’t for you.
