Sure, do: make clean all DEBUG=3Dtrue make install and set udev_log=3D"debug" in /etc/udev/udev.conf If you call udevstart on bootup, which is normally the one that creates /dev/null, you need to pass invoke it with: UDEV_LOG=3D8 /sbin/udevstart cause it does not follow the settings of the config, cause it may take minutes for it to finish cause of a slow syslog... You can also simply do (with the DEBUG compiled in): ACTION=ADd DEVPATH=3D/class/mem/zero UDEV_LOG=3D8 /sbin/udev mem and watch syslog to see what your rule does.
