Maybe udevd has not even been started then.  What does
"/usr/sbin/service udev status" say?

The udev init script has seen some changes in 239-8.  Offhand the only
one which could explain the problem is that systemd-udevd is now started
via start-stop-deamon[1].  I don't have any systemd-less system to test
myself, though.
