HP ProLiant m800 Server Cartridge uses GPIO gpio_key.12 for power control (key=116). The proposed patch adds entry to logind's 70-power-switch.rules to initiate soft shutdown of the cartridge from ilo. 

Here is the udevadm output for /dev/input/event0 

ubuntu at c3n1:~$ sudo udevadm info  --query=all --name=/dev/input/event0 --attribute-walk

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

  looking at device '/devices/soc.3/gpio_keys.12/input/input0/event0':
    KERNEL=="event0"
    SUBSYSTEM=="input"
    DRIVER==""

  looking at parent device '/devices/soc.3/gpio_keys.12/input/input0':
    KERNELS=="input0"
    SUBSYSTEMS=="input"
    DRIVERS==""
    ATTRS{name}=="gpio_keys.12"
    ATTRS{phys}=="gpio-keys/input0"
    ATTRS{uniq}==""
    ATTRS{properties}=="0"

  looking at parent device '/devices/soc.3/gpio_keys.12':
    KERNELS=="gpio_keys.12"
    SUBSYSTEMS=="platform"
    DRIVERS=="gpio-keys"
    ATTRS{keys}=="116"
    ATTRS{switches}==""
    ATTRS{disabled_keys}==""
    ATTRS{disabled_switches}==""

  looking at parent device '/devices/soc.3':
    KERNELS=="soc.3"
    SUBSYSTEMS=="platform"
    DRIVERS==""

ubuntu at c3n1:~$ 

This patch was tested by me and verified to work on HP m800 cartridge at Canonical.
