Hmm, what is this about? You need a place to load additional security
policies into the kernel at early boot? For SELinux that indeed takes
place from within PID 1 now in systemd. I'd expect that other security
technologies like AppArmor should work the same.

If you want to hack on this basing your work on selinux-setup.c in the
systemd tree should be fairly easy.
