To be honest, I'm still not convinced that this is the right way to
approach your problem. I think you would be much better off with
something analogous to the stripped-down SELinux policy I sent in an
earlier email (150 lines, give or take). By using the appropriate
SELinux hooks you can obtain the *exact* same enforcement, but without
adding any code to the kernel.

I have some time this week to split out my SELinux policy build
machinery; I will pull out a standalone set of files to build the
policy and do some extra testing on one of my bog-standard Debian
boxes and then send it all out again.

Cheers,
