Subject: REMOVE_CMD went missing during remove action events

I've started to use REMOVE_CMD in my udev scripts, but during my testing
I've noticed that the REMOVE_CMD doesn't get called.

Here is my udev rule which matches on a USB Bluetooth device, calls the
start function, and queues up the stop function via the REMOVE_CMD
environment variable.

ACTION=3D"add", KERNEL=3D"hci[0-9]*", SUBSYSTEM=3D"bluetooth",
ENV{REMOVE_CMD}=3D"/etc/init.d/bluetooth stop",
RUN+=3D"/etc/init.d/bluetooth start"

When the device is removed, the REMOVE_CMD environment variable is
missing. Is this expected behaviour?


# insert Bluetooth device, REMOVE_CMD is defined
UDEV  [883618587.004419] add    =20
