+# In the corresponding nix file, we have two derivations: the first, named root,
+# is a normal recursive derivation, while the second, named dependent, has the
+# new outputHashMode "text". Note that in "dependent", we don't refer to the
+# build output of root, but only to the path of the drv file. For this reason,
+# we only need to:
+#
+# - instantiate the root derivation
+# - build the dependent derivation
+# - check that the path of the output coincides with that of the original derivation
