+# They are already removed in postinst, but if configuration fails,
+# they will still be around.  Removing the package without
+# configuring would then allow the diversions to leak.
+#
+# So we catch them here.  This cannot wait for postrm because that
+# would break error recovery during upgrades: after the old, working
+# version re-adds the diversion in preinst, the diversion would be removed
+# again in postrm.  More generally, removing a diversion requires
+# a guarantee that the conflicting file is not present any more,
+# and we cannot guarantee that if some other version of
+# binutils-multiarch is installed.
