Introduction[edit]
We do enable AppArmor by default since Whonix ™ 9. This is done by the grub-enable-apparmor [archive] package.
A git branch to gather more information:
- https://github.com/Whonix/apparmor-profile-sdwdate/tree/debian-contributor-scripts-debug-output [archive]
- comes with two new files
