Yes selinux is still not playing nice with backuppc. I think the rpm of
backuppc includes a selinux policy
but i am not sure if that is installed by default.

I do know that this policy needs a lot of work, and in fact some time
ago i started creating a new policy for backuppc.
But i stumbled upon some packaging issues that i wanted resolved first
before i went ahead and complete the policy.

I never got to that point but i will consider revisiting backuppc policy.

I do still have my attempt for write policy for backuppc here:

git clone git://217.19.27.98/selinux-modules.git

But as said, it is incomplete.
