-# This is the unconfined template. This template is the base policy
-# which is used by daemons and other privileged components of
-# Android.
-#
-# Historically, this template was called "unconfined" because it
-# allowed the domain to do anything it wanted. Over time,
-# this has changed, and will continue to change in the future.
-# The rules in this file will be removed when no remaining
-# unconfined domains require it, or when the rules contradict
-# Android security best practices. Domains which need rules not
-# provided by the unconfined template should add them directly to
-# the relevant policy.
-#
-# The use of this template is discouraged.
