> Ubuntu should have taken a page from CoreOS, NixOS and even Arch. CoreOS with their immutable system partitions (and two of them so it can revert to a good one if the current can't boot). NixOS with the immutable packages (and the split between user and system packages). And even Arch with its release model. Actually Ubuntu Core is an edition of Ubuntu that has exactly these properties. It runs read-only, with packages that can be added and removed cleanly. This does involve moving away from apt/deb, which is fundamentally incapable of this. I don't know of any plans to do this for the main Ubuntu distro itself, but consider the resistance if this were on the roadmap.
