It's very unfortunate to hear about the package ID stuff. Is there a bug open? I managed to resolve the issue by getting rid of my parsec package as you advised. Unluckily it was depended on all the way from xmonad-extras. In the end I was able to remove -extras from my system as my config only needs -contrib, reboot, garbage collect and it works. I fear if this ever hits something xmonad directly depends on because I'll have to get rid of my WM to fix the issue… Perhaps a --force-overwrite flag should be created in nix-store as long as two hashes match?
