Estou tentando ativar o apparmor dentro do contêiner privilegiado, mas, por algum motivo, ele falha. Já habilitei o apparmor no kernel do host (4.9) e também no userspace (versão 2.11 do apparmor).
systemctl status apparmor -l logs

Também defini lxc.aa_profile = unconfined na configuração do meu contêiner.
Quaisquer sugestões serão apreciadas! Obrigado antecipadamente!
