> KDE Linux is an immutable distribution that uses Arch Linux packages as its base, but Graham notes that it is "definitely not an 'Arch-based distro!'" Pacman is not included, and Arch is used only for the base operating system. Everything else, he said, is either compiled from source using KDE Builder or installed using Flatpak.

Funny; sounds more like a BSD (a prebuilt single-artifact Arch "base system" + KDE Builder-based "ports collection") than a Linux.
