description "Replay critical udev events"
author ""
# This job is used to replay events of devices critical to the bring-up of
# the system. Since device nodes always exist, this is only needed if
# special permissions are required for nodes or special processing that
# would otherwise take place later.
# Subsystems listed here must be excluded from udev-trigger.conf to avoid
# replaying twice.
# Rationale:
# input - required to switch synaptics into raw mode, and also so X
# can initialize its input devices on startup rather than later
# misc - required if synaptics is already in raw mode
# graphics & drm - required to set permissions for accelerated graphics
# nvhost & tegra_dc_ext - on nVidia systems, X needs this
# tty - opened by powerd (running as user in "tty" group) at startup
# mem - kmsg opened by syslog service
# i2c-dev - Ensure /dev/i2c-* permissions are set for non-root firmware updaters
# hidraw - Ensure /dev/hidraw* permissions are set for non-root firmware
# updaters
# N.B. The 'boot-services' start on condition assumes this dependency on
# 'udev-boot'/'udev'. Don't change this line without accounting for the impact.
