[Buildroot] /run/udev missing ?

Hi,

after updating to latest buildroot, udevd has problems starting:

udevd[1114]: error: runtime directory '/run/udev' not writable, for now
falling back to '/dev/.udev'
udevd[1114]: failed to create queue file: No such file or directory
udevd[1114]: error creating queue file

It looks like udevd is not running or not working properly then as it
fails to load the firmware for the Wifi chip.

This is a configuration with static device management.

Any ideas? Should /run/udev exist or is the fallback OK and supposed to
work?
