The ignition pin can be used to wake the system from S3, S4, and S5 power states. The user can use the operating system power management to configure S3, S4, and S5 power states and shutdown.

NOTE: For more information about configuring the ignition pin (using the system.power-key-action command), see https://docs.ubuntu.com/core/en/reference/core-configuration.

Specify the action to take when the power button is pressed.

`kexec`	Direct-boot a new kernel
`suspend`	Suspend the system
