NAME

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

SYNOPSIS

10       systemd-udev-settle.service
11

DESCRIPTION

13       This service calls udevadm settle to wait until all events that have
14       been queued by udev(7) have been processed. It is a crude way to wait
15       until "all" hardware has been discovered. Services may pull in this
16       service and order themselves after it to wait for the udev queue to be
17       empty.
18
19       Using this service is not recommended.  There can be no guarantee that
20       hardware is fully discovered at any specific time, because the kernel
21       does hardware detection asynchronously, and certain buses and devices
22       take a very long time to become ready, and also additional hardware may
23       be plugged in at any time. Instead, services should subscribe to udev
24       events and react to any new hardware as it is discovered. Services
25       that, based on configuration, expect certain devices to appear, may
26       warn or report failure after a timeout. This timeout should be tailored
27       to the hardware type. Waiting for systemd-udev-settle.service usually
28       slows boot significantly, because it means waiting for all unrelated
29       events too.
