This is the default example configuration of usr.sbin.mysqld provided by MariaDB. This config file was generated by MariaDB running on Ubuntu 20.04.
It is located under: /etc/apparmor.d/usr.sbin.mysqld
# This file is intensionally empty to disable apparmor by default for newer
# versions of MariaDB, while providing seamless upgrade from older versions
# and from mysql, where apparmor is used.
# By default, we do not want to have any apparmor profile for the MariaDB
# server. It does not provide much useful functionality/security, and causes
# several problems for users who often are not even aware that apparmor
# exists and runs on their system.
# Users can modify and maintain their own profile, and in this case it will
# be used.
# When upgrading from previous version, users who modified the profile
# will be promptet to keep or discard it, while for default installs
# we will automatically disable the profile.
