Mikkel:
Modified, or added a local rule set. (Or had an extra rule set
left from an upgrade...)
Also, I probably didn't add a rule set (not manually, at least).
Btw, I noticed another file: /etc/udev/rules.d/51-hotplug.rules
# do not call hotplug.d and dev.d for "drivers" and "module" events
SUBSYSTEM=="drivers", GOTO="hotplug_end"
SUBSYSTEM=="module", GOTO="hotplug_end"
ACTION=="add", GOTO="hotplug_comp"
ACTION=="remove", GOTO="hotplug_comp"
GOTO="hotplug_end"
LABEL="hotplug_comp"
# compatibility support for the obsolete hotplug.d and dev.d directories
ENV{UDEVD_EVENT}=="1", RUN+="/lib/udev/udev_run_hotplugd"
RUN+="/lib/udev/udev_run_devd"
LABEL="hotplug_end"
