+Subject: [PATCH] Don't allow unhandled POSTs to write to the filesystem by
+ default
+
+If there's no registered handler for a POST request, the default behaviour
+is to write it to the filesystem. Several million deployed devices appear
+to have this behaviour, making it possible to (at least) store arbitrary
+data on them. Add a configure option that enables this behaviour, and change
+the default to just drop POSTs that aren't directly handled.
