+prs: 4093
+---
+
+Add a new `eval-system` option.
+Unlike `system`, it just overrides the value of `builtins.currentSystem`.
+This is more useful than overriding `system`, because you can build these derivations on remote builders which can work on the given system.
+In contrast, `system` also effects scheduling which will cause Nix to build those derivations locally even if that doesn't make sense.
+
+`eval-system` only takes effect if it is non-empty. If empty (the default) `system` is used as before, so there is no breakage.
