  ### TODO: AppArmor doesn't give us the chance to attach a separate profile
  ### depending on the executable symlink. That's possible with SELinux. Two
  ### alternatives: implement that in AppArmor, or consider aa_change_hat(2).
  ### With this, rules for passt(1) could be restricted significantly. Note that
  ### the attach_disconnected flag is not needed for passt(1).
