A review of Nix/NixOS after using it on all my machines for three years. I'll cover what works, what doesn't, and why it's the first OS that's stuck with me.
I have not used Nix, so I may not know what I am talking about.
That said, I have been using Chimera Linux which uses the APK package manager. It works by maintaining a single file in /etc/apk/world that specifies all the packages the user wants on the system. This is used to calculate dependencies and install packages. When you “add” and “del” packages, all it is really doing is adding and removing from this list. If you remove a package, it will remove all the dependencies too unless they appear in the “world” file.
If you do not specify a version number for a package, you get the latest. But you can pin versions of you want.
If you copy the world file from one system to another, you get the same set of installed packages.
So, if I use git to backup my world file, maybe a couple of other entries in /etc, and the dot files in my home directory, I have pretty much everything I need to completely recreate my system.
Is it really worth all the extra complexity of Nix?
