What does an average Linux distribution look like? Generally, it’s like a system assembled from thousands of packages, with additional desktop interface tweaks, possibly its own installer, and configuration system. In essence, most distributions are quite similar and are built on the same idea: package + package + package = OS. Endless is entirely different—it has no traditional packages. Instead, it features a concept of an atomically updatable core system and uses Flatpak sandboxes for applications.
