+Check that Dune help commands that understand BUILD_PATH_PREFIX_MAP to
+rewrite the current working directory:
+
+  $ echo '(lang dune 3.0)' > dune-project
+  $ cat > dune <<"EOF"
+  > (rule
+  >  (target x)
+  >  (action (system "dune_cmd rewrite-path $PWD; touch x")))
+  > EOF
+
+  $ dune build
+  /workspace_root
+
+It works with sandboxing as well:
+
+  $ dune clean
+  $ dune build --sandbox copy
+  /workspace_root
