"Why is it implemented in 3 different languages: Nix, Bash and C?"
And he's right, it doesn't make sense, because we were using C as a
runuser replacement and used Nix to generate the shellscript
boilerplates.
Writing this in Python gets rid of all of this and we also don't need
the boilerplate as well, because we're using Click to handle all the
command line stuff.
Note that this currently is a 1:1 implementation of what we had before.
