/usr/sbin/apache2 flags=(complain) {
  # This profile is completely permissive.
  # It is designed to target specific applications using mod_apparmor,
  # hats, and the apache2.d directory.
  #
  # In order to enable this profile, you must:
  #
  # 1- Enable it:
  #    sudo aa-enforce /etc/apparmor.d/usr.sbin.apache2
  #
  # 2- Load the mpm_prefork and mod_apparmor modules:
  #    sudo a2dismod <other non-prefork mpm>
  #    sudo a2enmod mpm_prefork
  #    sudo a2enmod apparmor
  #    sudo service apache2 restart
  #
  # 3- Place an appropriate profile containing the desired hat in the
  #    /etc/apparmor.d/apache2.d directory.  Such profiles should probably
  #    include the "apache2-common" abstraction.
  #
  # 4- Use the "AADefaultHatName" apache configuration option to specify a
  #    hat to be used for a given apache virtualhost or "AAHatName" for
  #    a given apache directory or location directive.
  #
  #
  # There is an example profile for phpsysinfo included in the
  # apparmor-profiles package. To try it:
  #
  # 1- Install the phpsysinfo and the apparmor-profiles packages:
  #    sudo apt-get install phpsysinfo apparmor-profiles
  #
  # 2- Enable the main apache2 profile
  #    sudo aa-enforce /etc/apparmor.d/usr.sbin.apache2
  #
  # 3- Configure apache with the following:
  #    <Directory /var/www/phpsysinfo/>
  #        AAHatName phpsysinfo
  #    </Directory>
