+!!! warning
+
+    Do not put Nix store paths into global/pipeline variables. They will simply be passed through,
+    resulting in bad portability (if two runners have different archs for example, one cannot find the path).
+    If you need any Nix store path in env variables, always do it on the job level, there
+    it will automatically be computed at runtime, thus will always work no matter which runner it runs on.
