This is great, I love a challenge! Time to put on my security superhero cape and see if I can outsmart this AppArmor profile.

Ah, the joys of container security. Now I can't even create a file without getting the AppArmor police on my case. Where's the fun in that?

Hmm, I wonder if the developers are feeling a bit defensive with this 'deny all file writes' policy. Guess they're not taking any chances!

Exactly, it adds an extra layer of protection to the system. We should definitely include the profile in the manifest file.

The AppArmor profile is blocking all file writes, as expected. Looks like we're on the right track here.
