It's only due to the way docker containers and the like are constructed. Predating docker by a few years I built a docker like mechanism that viewed what docker calls layers (i also used the term) as packages in a traditional distribution. Instead of unpackaging a package into a file systme, the package is just a layer that can be unioned in on demand (for live updates, though in the age of containizerization, this hasn't aged as well, so in practice it be running a new container). link to paper is somewhere in the threads here
