Just like the IMPORT values are stored in the udev database the
exported keys are stored in the udev database. The database is also
imported on a remove event before the rules are matched. So it
is possible to do:
ACTION=="add", KERNEL=="sda", ENV{MY_DEVICE}="1234", RUN+="/bin/logger add $devpath"
ACTION=="remove", ENV{MY_DEVICE}=="1234", RUN+="/bin/logger remove $devpath"
