This is a good example of what people consistently overlook/misunderstand, when it comes to Nix.
Obviously you can remount a /home, or just pull the dotfiles from a personal repo, but the strength of Nix is also in that I can re-create my entire config exactly how it is defined. If i were to setup a machine completely from scratch, with a mature enough config, it will get me from 0 to my exact desktop completely unattended.
But there are also many more advantages to it, at least in my eyes. Let's take trying/tweaking new packages as an example. Yesterday I pulled an old repo for an Outer Wilds mod. The thing needs a dev environment, and a mod manager for the actual game. A nix shell
got me both, I finished my work, and when I exit out of fish, both are gone, just as I wanted them to be.
Another good example would be partial os updates. I've used Arch for almost 9 years before switching to Nix, and pretty much a top3 Arch rule is not doing partial updates, or partial rollbacks. In case of a breakage, I would have to manually redownload an older version of a tarball, pacman -U
the package, and then hope i'm not cooked. In the case of gcc incompatibilities, it can quickly become a massive pain in the ass. My nix flake would never experience this problem, because I already have two different scenarios available - either i build based on an older lockfile from my git repo, or I create an overlay for a specific input I need, so that it still pulls what it needs, and doesn't interfere with the rest of my system
