+Subject: [PATCH] po-docs: Make sure guestmount.1 depends on includes
+
+guestmount.1 depends on translated files blocksize-option.pod,
+key-option.pod & keys-from-stdin-option.pod (via __INCLUDE__
+directives).  If these are not yet translated by the time we try to
+generate guestmount.1 then it will fail with:
+
+podwrapper.pl: key-option.pod: cannot find input file on path at /builddir/build/BUILD/libguestfs-1.50.1/podwrapper.pl line 672.
+
+This happens especially in parallel builds.  Fix this by writing the
+guestmount.1 rule explicitly, with the correct dependencies.
+
+(cherry picked from commit 87b4d19f851feee2ea5776421e216a8c541b4355)
