nodedev-autostart
-----------------
**Syntax:**
::
nodedev-autostart [--disable] device
Configure a device to be automatically started when the host machine boots or
the parent device becomes available. With *--disable*, the device will be set
to manual mode and will no longer be automatically started by the host. This
command is only supported for persistently-defined mediated devices.
