# vim:syntax=apparmor
# Profile abstraction for restricting chromium in the lightdm guest session
# Author: Jamie Strandboge <jamie@canonical.com>
# The abstraction provides the additional accesses required to launch
# chromium based browsers from within an lightdm session. Because AppArmor
# cannot yet merge profiles and because we want to utilize the access rules
# provided in abstractions/lightdm, this abstraction must be separate from
# abstractions/lightdm.
# Requires apparmor 2.9
