As a counterpoint, a disadvantage of deb/rpm is that the installed code can actually scribble crap anywhere they like in your system. Did you just install a setuid program? Did it just install a service? Who knows!

As much as I’m not a fan of Docker, it does isolate the container’s file system and other resources from the OS, something that deb/rpm/brew etc don’t do.

I’ve been meaning to check out Nix for awhile for this exact reason. I want the state of my operating system to be a simple state machine managed by a package manager. Right now the filesystem on Ubuntu and friends it feels like a horrible mess of random stuff. You end up in a different OS state if apt fails halfway through installing, or if you install an old package, configure it then upgrade it vs installing a new package. The classic “make install” just puts files wherever it wants. And then there’s the layered complexity of language-specific package managers - which are needed because apt isn’t up to task.

This is one big advantage of docker. Applications are actually portable and isolated. We need more of that in our Linux distributions.

You can unpack those formats with `bsdtar xf PACKAGE` and that's something that is much harder to do with Docker.

I'm not sure if I understand the advantage here. Aren't container images trivial to export? I've done this many times as part of build pipelines
