# This is a system unit for launching AGL compositor with auto-login as the
# user configured here.
#
# AGL compositor and Weston must be built with systemd support, and your
# weston.ini must load the plugin systemd-notify.so.
#
# Attention:
# If you will add new tty dependency setting, you need to update 
# agl-compositor-guest.conf.
