NAME

       systemd-udev-settle.service - Wait for all pending udev events to be handled

SYNOPSIS

       systemd-udev-settle.service

DESCRIPTION

       This service calls udevadm settle to wait until all events that have been queued by
       udev(7) have been processed. It is a crude way to wait until "all" hardware has been
       discovered. Services may pull in this service and order themselves after it to wait for
       the udev queue to be empty.

       Using this service is not recommended.  There can be no guarantee that hardware is fully
       discovered at any specific time, because the kernel does hardware detection
       asynchronously, and certain buses and devices take a very long time to become ready, and
       also additional hardware may be plugged in at any time. Instead, services should subscribe
       to udev events and react to any new hardware as it is discovered. Services that, based on
       configuration, expect certain devices to appear, may warn or report failure after a
       timeout. This timeout should be tailored to the hardware type. Waiting for
       systemd-udev-settle.service usually slows boot significantly, because it means waiting for
       all unrelated events too.
