no changes to udev rules. and this happens immediately after the update
is run, no reboot required. what is weird is that the config on the
systems i run are pretty close to each other, so why only a few got hit
by this is odd. i had one happen yesterday and thought i had just done
something stupid, but then more popped up today immediately after doing
updates, so that is why the warning.
