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.

    It doesn’t use the system libraries, unless the system in question is NixOS. It still provides its own dependencies. Arguably in a more elegant and less wasteful manner, but they are still distinct from the ones used by the rest of the system.

      To be more clear, it uses a weird combination of your system libraries, installing its own libraries into your system on its own without informing your primary package manager, and using some specific library versions separate from your system libraries for some apps.

      If you want to call that more “elegant” than other solutions… Well, I can’t tell you how to feel about something. It still doesn’t actually solve the problem that universal package formats are trying to solve unless the package dev explicitly requires so many specific library versions that the whole thing just ends up being an AppImage with extra steps though.

        The packager always should “explicitly require” what are the dependencies in a Nix package… it’s not like it’s a choice, if there are missing dependencies then that’d be a bug.

        If the package is not declaring its dependencies properly then it might not run properly in NixOS, since there are no “system libraries” in that OS other than the ones that were installed from Nix packages.

        And one of its advantages over AppImages is that instead of bundling everything together causing redundancies and inefficient use of resources, you actually have shared libraries with Nix (not the system ones, but Nix dependencies). If you have multiple AppImages that bundle the same libraries you can end up having the exact same version of the library installed multiple times (or loaded in memory, when running). Appimages do not scale, you would be wasting a lot of resources if you were to make heavy use of them, whereas with Nix you can run an entire OS built with Nix packages.
