> While some Linux purists dislike containerized application installation programs such as Flatpak, Snap, and AppImage, developers love them. Why? They make it simple to write applications for Linux that don't need to be tuned just right for all the numerous Linux distributions.
The good thing is that for end users, Guix and Nix (as package managers) do cover exactly the same set of features - but both are much friendlier to developers than containerized apps. And of course they are truly FLOSS and "open source" in that stuff is built from source and that sources are readily available to the users. This matters, since this makes the software more friendly: It is user-friendly because it is written by the users, in difference to a party which has other things as their top priority.
