+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 any path component is used in a ATTR{}, ATTRS{},
+ $attr{} key, like ATTR{device/<file>}==
+ (parent attributes must not referenced directly in rules or tools,
+ udev finds the parents and makes them available, which can be matched
+ with the normal keys)
+
+ o warn if BUS, ID, SYSFS are used as keys
+ (they are SUBSYSTEMS, KERNELS, ATTRS now)
