udevd had the ability to delay name resolution until the event, but this was never exposed. Add a --resolve-names=late option to do so.

|
|
<para>udevd listens to kernel uevents and passes the incoming events to
|
|
udev. It ensures the correct event order and takes care, that events for child
|
|
devices are delayed until the parent event has finished the device handling.
|
|
The behavior of the running daemon can be changed with
|
|
<command>udevadm control</command>.</para>

actions or loads kernel modules which cause problems and a slow but continuous
