+# Description: when a file in a deep directory disappeared during creation
+# of incremental dump, tar v. <1.23 would exit with TAREXIT_FAILURE (2).
+# However, such events are quite common and don't necessarily constitute
+# an error.  Exiting with code 2 in such cases makes it impossible to
+# distinguish serious errors from benign ones.
+#
+# Starting from tar 1.22.90, tar exits with TAREXIT_DIFFERS (1)
+# instead.
