+ any of the links at that time
+
+These things will change in future udev versions:
+ o make DRIVER== to match only the event device
+ (DRIVERS must be used, we currently translate it to DRIVERS and print
+ a warning if DRIVER is used)
+
+ o warn if PHYSDEV* keys are used in ENV keys
+ (they are deprecated and will be removed from a future kernel)
+
+ o warn if "device/" is used in a ATTR{}, ATTRS{}, $attr{} key
+ (the device link must not be used in rules or tools, udev resolves
+ the link and makes the devices available as parents, which can
+ be matched with the normal keys)
+
+ o warn if BUS, ID, SYSFS are used as keys
+ (they are SUBSYSTEMS, KERNELS, ATTRS now)
