|
.SH NAME
|
|
udevd, udevdsend \- udev event serializer daemon and udev event sender
|
|
.SH SYNOPSIS
|
|
.BI udevsend
|
|
.SH "DESCRIPTION"
|
|
.B udevd
|
|
allows the serialization of
|
|
.BR hotplug (8)
|
|
events. The events generated by the kernel may arrive in random order
|
|
in userspace, that makes it neccessary to reorder them.
|
|
.br
|
|
.B udevd
|
|
takes care of the kernel supplied
|
|
.B SEQNUM
|
|
sequence number and arranges the events for execution in the correct order.
|
|
Missing sequences delay the execution of the following events until a timeout
|
|
is reached. Events without any sequence number are bypassing the queue and
|
|
will be executed immediately.
|
|
.br
|
|
For each event a
|
|
.BR udev (8)
|
|
instance is executed in the background with the complete environment received
|
|
by the hotplug event. All further events for the same device are delayed until
|
|
the execution is finished. This way there will never be more than one instance
|
|
running for a single device at the same time.
|
|
.br
|
|
.B udevd
|
|
receives the events from
|
|
.B udevsend
|
|
If
|
|
.B udevd
|
|
isn't already running,
|
|
.B udevsend
|
|
will start it.
