 Just to clarify --- this is the latest kernel patch snapshot?

 I'm not surprised that it's something like this; just surprised that
 -A would work and subsequent attempts to use the policy would fail
 silently!
 
 I'm very surprised that I'm not getting any syslog messages
 from any of this; that there are not "verbose" options to the systrace
 binary, and that there isn't even a -V (--version) option!
