http://serverfault.com – I am running a Ubuntu 12.04 server with Apache using mod_apparmor. When I run aa-status, I see thousands and thousands of profiles with names like /usr/lib/apache2/mpm-prefork/apache2//DEFAULT_URI//null-12b08 Some of them even stack: /usr/lib/apache2/mpm-prefork/apache2//scoop//null-2dd76//null-2dd77 What are these? Are they actually hats? (HowTos)
