I administer thousands of selinux boxes professionally. I, like the vast majority of Earth's population, remain steadfastly uninterested in Fedora's default behavior.

You claim that OpenBSD has no conpromised-root mitigation. I have provided evidence to back my counterclaim. I will assume your rejection of actual evidence indicates a disinterest in good-faith argument, so I won't bother pressing the point, except to mention that you may be more successful persuading people to support your case if you adopt a reality-based approach to argument instead of just making wild-ass assumptions about other people.
