Portable, dynamically linked packages on Linux
Which means we can just put this directory anywhere on the file system and it’ll run… including in a container image. Presto, behold a Dockerfile!
Save it as Dockerfile (or Containerfile), build it with Podman / Docker / etc, and it still runs, even in the completely barren scratch environment:
Well, I care, for one! I’m a weirdo trying to build a package manager. And building a package manager means… putting packages on people’s computers, so you need to figure out where to put the package on the computer. Being able to put the package anywhere makes it easier!
Depending on how much you know about dynamic linking, it should seem impossible for all 3 of these things to be true. Let’s ignore the how for now and talk about why I made it work this way:
So hopefully you can see how the little party trick with curl came to be: to tick all the boxes for Brioche, I had to make that trick work. Every package in Brioche works this way, too. You can just put any package into a directory somewhere on your filesystem, and it’ll run entirely self-contained even for a completely bare-bones Linux setup
