testing/fprobe-ulog/fprobe-1.1-pidfile-sanity.patch

+If we are using the chroot() option or the setuid options, we must create the
+pidfile before doing the chroot OR the setreuid. It's actually best for
+start-stop-daemon if we create the pidfile from the master side of the fork()
+before it exits, since most of the startup checks happen after the chroot()
+unfortunetly.
