220: Drop flattenTreeSystem and use custom function for filtering packages r=nrdxp a=Pacman99 I don't think we should flatten the system because if a user doesn't make a package a derivation in pkgs/default.nix we should trust that there is a reason for doing so. So instead this drops the flattenTreeSystem reference(and switches to flake-utils master branch) and replaces its usage with a custom function `filterPackages`. This function filter all packages that match three conditions; - is a derivation - not broken - system is supported In that order as to not cause errors when trying to reference non-derivation meta attributes. And then also just dump *all* packages into legacy packages, so everything else is still accessible. I was considering removing the packages that are already in the packages output in legacyPackages, but I don't think its necessary since nix looks to the packages output first.
