I really like the desktop environment they have developed, Cinnamon. But I agree with this LWN thread about their broken approach to packaging. Furthermore, I tend to find people commenting in LWN really respectful even if they are critical, as it was the case here.

We are currently going through a bit of a Cambrian explosion of Linux distributions, but some do have indeed shaky technical foundations. Many distributions would fare much better if they were built as a thin layer on top of something clean and reproducible like Gentoo, Arch or, ideally, GuixSD/NixOS.

In reality, we are seeing lots of distributions, like Mint, as a layer on top of Ubuntu. Which in turn is based on Debian. Seasoned users like those posting on LWN find this frustrating as it obscures things a lot.

Personally, I have not seen good technical foundations for Linux distributions aside from things that have either a very simple imperative architecture (like Arch) or purely functional (Nix/Guix).
