+## 72_xdev_is_non_positional.dpatch by Ian Campbell <ijc@debian.org>
+##
+## All lines beginning with `## DP:' are a description of the patch.
+## DP: Bug #916602 patch by Ian Campbell <ijc@debian.org>
+## DP:
+## DP: find issues a warning when `traverse_fs = "false"` is combined with
+## DP: pruning:
+## DP:     find: warning: you have specified the -xdev option after a non-option argument -regex, but options are not positional (-xdev affects tests specified before it as well as those specified after it).  Please specify options before other arguments.
+## DP:
+## DP: Resolve this by moving the use of `-xdev` before the `-regex` calls
+## DP: produced by pruning. However it is not possible move the `-fstype` used
+## DP: for the `traverse_fs = "local"` case (or, presumably, "all" although I
+## DP: did not test this) since this changes the semantics and therefore the set
+## DP: of files backed up in my testing.
