A while ago we moved hotplug.d/ handling into udev to be able to plug
HAL into the hotplug process and get rid of the hotplug/sysfs races.
Now we removed that from udev itself again, cause with udev-rules you
can do the same as hotplug.d/ did without all the problems of matching
only on the subsystem.
You can still use the old hotplug multiplexer or put a small helper
from the extras/run_directory/ into a udev rule that runs the hotplug.d/
programs.

I'm not sure what you mean. If you specify a NAME rule, RUN will also
be called, but if you use NAME, no other action than "add" can ever
trigger that rule. So if you want to call a script for a specific device
for _all_ actions and rename the device at the same time, just use two rules,
one for the name and one for the "generic" RUN.
I think the best way to do this is to add two rules, one for "add" and
one for "remove".
