REMOVE_CMD went missing during remove action events

REMOVE_CMD went missing during remove action events

[Aras Vaichas]

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="add", KERNEL="hci[0-9]*", SUBSYSTEM="bluetooth",
ENV{REMOVE_CMD}="/etc/init.d/bluetooth stop",
RUN+="/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     
/devices/platform/at91_ohci/usb1/1-1/1-1:1.0/hci0 (bluetooth)
UDEV_LOG=3
ACTION­d
DEVPATH=/devices/platform/at91_ohci/usb1/1-1/1-1:1.0/hci0
SUBSYSTEM=bluetooth
SEQNUMW5
UDEVD_EVENT=1
REMOVE_CMD=/etc/init.d/bluetooth stop

# remove Bluetooth device, REMOVE_CMD is missing
UDEV  [883618588.926582] remove  
/devices/platform/at91_ohci/usb1/1-1/1-1:1.0/hci0 (bluetooth)
UDEV_LOG=3
ACTION=remove
DEVPATH=/devices/platform/at91_ohci/usb1/1-1/1-1:1.0/hci0
SUBSYSTEM=bluetooth

UDEVD_EVENT=1
