This is the master branch of nixpkgs, initially pulled from commit 8debf2f9a63d54ae4f28994290437ba54c681c7b
The intent of this repo is to be merged onto nixpkgs master. This will also be of help for https://git.suyu.dev/BoomMicrophone/suyu-nix-test
which I will need in order for development (it will also be helpful to know what to do for setting up the environment for the master server. Currently I am focusing on this so I can actually see what is still missing)
This repo will be removed once the PR to the nixpkgs github goes through

problem: the nix language assert function can't be used because
of the fix-style used in modular-nixos. A minimal stripped down version
illustrating the problem looks like this:
fix (x : assert x.cfg.foo; { upstartJob = ...; cfg = ...; } )
Now nix has to evaluate x.cfg.foo in order to check the assertion.
However to do so it has to access x.cfg.foo beeing defined in the body
The body can only be evaluated after the assertion passes.
So in the end you get an infinite recursion error.
pierron mentioned that adding another mkIf like function could
work. Maybe this implementation is even simpler. It adds
another option collecting assertions only.
The evaluation is forced by a function adding an empty list to
extraPackages. extraPackages is evaluated by nixos in all cases.
If there are assertions evaluating to false all assertion messages are
presented to the user using throw.
