Currently, even if you pass `supportedSystems = [ "aarch64-linux" ]` you end up with e.g. `nixos.iso_graphical.x86_64-linux` job. Using forTheseSystems from release-lib avoids that. This shouldn't affect the usual x86 trunk-combined jobset.
*** NixOS *** NixOS is a Linux distribution based on the purely functional package management system Nix. More information can be found at http://nixos.org/nixos and in the manual in doc/manual.
