Distro agnostic packages like flatpaks and appimages have become extremely popular over the past few years, yet they seem to get a lot of dirt thrown on them because they are super bloated (since they bring all their dependencies with them).
NixPkgs are also distro agnostic, but they are about as light as regular system packages (.deb/.rpm/.PKG) all the while having an impressive 80 000 packages in their repos.
I don’t get why more people aren’t using them, sure they do need some tweaking but so do flatpaks, my main theory is that there are no graphical installer for them and the CLI installer is lacking (no progress bar, no ETA, strange syntax) I’m also scared that there is a downside to them I dont know about.
I’m going to go against the grain and say that the Nix and Guix package managers are very good, but they really belong in their respective distros where they’re a core part of the system. That’d be Guix System for Guix and NixOS for Nix.
They may have advantages for a foreign distro too, but they are lesser (Guix System can boot into a backup of the system before the last update, for example, but that advantage doesn’t exist on, say, Debian.
Also, can we agree to not recommend these systems to new users for the time being? While they’re very powerful, they’re absolutely designed for power users, and until they’re more polished and they have fancy GUIs and stuff for installation and package management, I think it’d be best to keep recommending normal distros like Debian for now.
You can do rollbacks if you’re using something like home-manager on a foreign distribution. It’s just a bit more janky admittedly.
