Hrmm, this was clearly an oversight on my part:

  [ Jamie Strandboge ]
  * debian/patches/update-base-abstraction-for-signals-and-ptrace.patch:
    Adjust the base abstraction for signals and ptrace mediation. Profiles
    that use the base abstraction can deny any of the granted permissions to
    achieve tighter confinement.

I've taken a todo to post this to the list. Sorry...
