I'd say that this is a good first step, but I think it has a problem. It has the same limitations as conditional policy, since you're reusing those data structures. I'd like to be able to put more in tunables than can be put in conditional policy blocks, such as rbac (role, role allow, role_transition) statements and typeattributes statements. -- Chris PeBenito Tresys Technology, LLC www.tresys.com | oss.tresys.com -- This message was distributed to subscribers of the selinux mailing list.
