Name one distro apart from the EL clones that offer MAC policies for the software in the core repos. SELinux in Debian is a joke, so are the AppArmor policies.
The tangle of suse/opensuse is confusing to me, but I know that the opinionated rolling versions like MicroOS, Aeon, and Kalpa standardized on SELinux. And I know that there are policies for both AA and SELinux for at least some software in the repo.
