[DSE-Dev] Bug#668954: not a serious bug, just a new feature that doesn't work.

severity 668954 minor
thanks
I can't get the policy for this written for Wheezy. I've attached a policy
patch for a work in progress so anyone who is interested can work on it for
their own purposes.
I'll get this going post-Wheezy with a new policy tree from upstream. For
Wheezy I think I'll just remove the sandbox program from policycoreutils as
there's no way of making it do anything useful.
This isn't an important issue as it's a new feature that has never worked.
Everything else in policycoreutils has worked well without this and will
continue to work without it.
