Is SELinux compatible with AppArmor?

The Linux Kernel provides the Linux Security Module interface, of which SELinux and AppArmor are both implementations of. (Others include TOMOYO, Smack, …) This interface is designed currently to only allow a single LSM to be operational at a time. There is no way to run two simultaneously, so you must choose one.
