| description "Replay critical udev events" |
| author "chromium-os-dev@chromium.org" |
| |
| # 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 |
| # tty0 - opened by powerd (running as user in "tty" group) at startup |
| # tty1, tty2 - needed by X server |
| |
| # N.B. The 'boot-services' start on condition assumes this |
| # dependency on 'udev'. Don't change this line without accounting |
| # for the impact. |
| start on started udev |
