John Ericson 9f9723b179 nixpkgs module: Fix defaulting of localSystem and system ... Take two of #40708 (4fe2898608). That PR attempted to bidirectionally default `config.nixpkgs.system` and `config.nixpkgs.localSystem.system` to each be updated by the other. But this is not possible with the way the module system works. Divergence in certain cases in inevitable. This PR is more conservative and just has `system` default `localSystem` and `localSystem` make the final call as-is. This solves a number of issues. - `localSystem` completely overrides `system`, just like with nixpkgs proper. There is no need to specify `localSystem.system` to clobber the old system. - `config.nixpkgs.localSystem` is exactly what is passed to nixpkgs. No spooky steps. - `config.nixpkgs.localSystem` is elaborated just as nixpkgs would so that all attributes are available, not just the ones the user specified. The remaining issue is just that `config.nixpkgs.system` doesn't update based on `config.nixpkgs.localSystem.system`. It should never be referred to lest it is a bogus stale value because `config.nixpkgs.localSystem` overwrites it. Fixes #46320		2018-09-07 16:43:56 -04:00
