Hi there, we use apparmor on our production systems and want to test the setup in our test environment based on systemd-nspawn. Therefore, I installed apparmor on the host (debian stretch) and updated GRUB_CMDLINE_LINUX in /etc/default/grub to enable apparmor. I can use apparmor on the host system. However, within my containers, apparmor can not be started. `journalctl -kf` does not print anything when invoking `systemctl start apparmor` on the container and `systemctl status apparmor` just returns "ConditionSecurity=apparmor was not met". Is it possible to run apparmor in a container? Cheers, Matthias
