[Impact]

The package is new to the releases and sets up EC2 on demand instances to hibernate on an ACPI sleep event.

[Test Case]

Please perform piuparts-like tests with the package and make sure that ec2-hibinit-agent service is started. On EC2 on demand instances that were configured to allow hibernation the hibinit-agent service prepares the system for enabling hibernation. On non EC2 on demand instances and on EC2 on demand instances where hibernation is not configures when launching the instance the service starts without error but does not prepare the system for being able to hibernate.

[Regression Potential]

Since the package is new it may not cause regressions by being broken.

The package sets up a swap file on / reserving the size of the memory from the root partition. There is check in the service to ensure that there is enough space but the space left may not be enough for the proper operation of the system later. Users a warned on EC2 console to allocate a big enough root partition for the instance when instance hibernation is enabled.
