+Test the behaviour of Dune querying git when the repo has no commit.
+
+Create a repository with no HEAD commit:
+
+  $ git init --quiet
+
+... and an executable that links `dune-build-info':
+
+  $ echo "(lang dune 2.0)" > dune-project
+  $ touch main.ml
+  $ cat >dune <<EOF
+  > (executable
+  >  (name main)
+  >  (libraries dune-build-info)
+  >  (promote (until-clean)))
+  > EOF
+
+Dune handles this gracefully since #4441
+
+  $ dune exec ./main.exe 2>&1
