It takes work because the design of FHS is outdated and will eventually die off when we have working package managers that can deal with incoherency of their packages, and figure out a less heavy handed approach to redundancy. Containerization isn't really the answer but it uses the same tools that the answer will have: chroot jails, Linux namespaces, and bind mounts + overlays. The problem with containers is that the layer model doesn't lead to anything actually being shared, but the basic feature set of the user lane gives the tools to a possible solution that doesn't suck. Nix is close, but suffers from design issues orthogonal to how it works. Maybe Nixos is the future once end users never need to read a flake.
