+Setting (expand_aliases_in_sandbox) should re-run the action
+
+First, we create an action and make it depend on an alias
+
+  $ cat >dune-project <<EOF
+  > (lang dune 3.11)
+  > EOF
+  $ export DUNE_SANDBOX=symlink
+  $ cat >dune <<EOF
+  > (rule
+  >  (alias bar)
+  >  (action (with-stdout-to alias-dep (echo ""))))
+  > (rule
+  >  (alias foo)
+  >  (deps (alias bar))
+  >  (action (system "find . | sort")))
+  > EOF
+  $ dune build @foo
+  .
+
+Now we set (expand_aliases_in_sandbox), and re-run the action.
+
+  $ cat >dune-project <<EOF
+  > (lang dune 3.11)
+  > (expand_aliases_in_sandbox)
+  > EOF
+  $ dune build @foo
+  .
+  ./alias-dep
+
+The above output should include the files that we depend on via the alias
+expansion.
