+Subject: [PATCH] Makefile.am: Avoid redirection of input and output files
+
+Ensure that directory is created before its written to
+
+This can cause a build race in a highly parallelised build where a directory is not yet created but
+output file is being written using redirection e.g.
+
+rst2man.py --strict --no-raw --no-generator --no-datestamp < ../git/monitor/iwmon.rst > monitor/iwmon.1
+/bin/sh: monitor/iwmon.1: No such file or directory
+make[1]: *** [Makefile:3544: monitor/iwmon.1] Error 1
+
+Upstream-Status: Pending
